Palpitations are uncomfortable sensations of the heart beating hard, rapidly, or irregularly. Some types of palpitations are benign, while others are more serious. Palpitations are diagnosed by taking the patient history and by performing an EKG or heart monitoring along with blood tests. An electrophysiology study may also be performed. Treatment of palpitations may include lifestyle changes, medication, ablation, or implantation of a pacemaker. The prognosis if palpitations depends on the underlying cause.

Low Blood Pressure (Hypotension)
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, and fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Kidney (Renal) Failure
Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure include sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis. Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones.Treatment options included diet, medications, or dialysis.
Thyroid Disorders Symptoms and Signs
Thyroid diseases and disorders are caused because the body either makes too much or too little thyroid hormones, which are necessary for vital functions of the body. Thyroid disease and disorder symptoms and signs depend on the type of the thyroid problem. Examples include heat or cold intolerance, sweating, weight loss or gain, palpitations, fatigue, dry skin, constipation, brittle hair, joint aches and pains, heart palpitations, edema, feeling bloated, puffiness in the face, reduced menstrual flow, changes in the frequency of bowel movements and habits, high cholesterol, hoarseness, brittle hair, difficulty swallowing, shortness of breath, a visible lump or swelling in the neck, tremors, memory problems, depression, nervousness, agitation, irritability, or poor concentration. Thyroid problems are more common in women.
Hyperthyroidism is an excess of thyroid hormone due to an overactive thyroid gland. Symptoms can include increased heart rate, weight loss, heart palpitations, frequent bowel movements, depression, fatigue, fine or brittle hair, sleep problems, thinning skin, and irregular vaginal bleeding. Graves' disease is the most common cause of hyperthyroidism. Many other health problems or taking excess thyroid hormone medication can cause an overactive thyroid gland. Treatment for the condition is with medication, radioactive iodine, thyroid surgery (rarely), or reducing the dose of thyroid hormone. No diet has been shown to treat hyperthyroidism or its symptoms and signs.
Pregnancy (Week by Week, Trimesters)
Signs and symptoms of pregnancy vary by stage (trimester). The earliest pregnancy symptom is typically a missed period, but others include breast swelling and tenderness, nausea and sometimes vomiting, fatigue, and bloating. Second trimester symptoms include backache, weight gain, itching, and possible stretch marks. Third trimester symptoms are additional weight gain, heartburn, hemorrhoids, swelling of the ankles, fingers, and face, breast tenderness, and trouble sleeping. Eating a healthy diet, getting a moderate amount of exercise, also are recommended for a healthy pregnancy. Information about the week by week growth of your baby in the womb are provided.
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. There are several types of anemia such as iron deficiency anemia (the most common type), sickle cell anemia, vitamin B12 anemia, pernicious anemia, and aplastic anemia. Symptoms of anemia may include fatigue, malaise, hair loss, palpitations, menstruation, and medications. Treatment for anemia includes treating the underlying cause for the condition. Iron supplements, vitamin B12 injections, and certain medications may also be necessary.
Ticks are known transmitters of disease to humans and animals. Tick-borne diseases include Lyme disease, Rocky Mountain spotted fever, Q fever, tularemia, babesiosis, and Southern tick-associated rash illness. Infected ticks spread disease once they've bitten a host, allowing the pathogens in their saliva and mouth get into the host's skin and blood. Tick bites are typically painless, but the site of the bite may later itch, burn, turn red, and feel painful. Individuals allergic to tick bites may develop a rash, swelling, shortness of breath, numbness, or paralysis. Tick bite treatment involves cleaning and applying antibiotic cream.
How the Heart Works (Sides, Chambers, and Function)
The heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.
An arrhythmia is an abnormal heart rhythm. With an arrhythmia, the heartbeats may be irregular or too slow (bradycardia), to rapid (tachycardia), or too early. When a single heartbeat occurs earlier than normal, it is called a premature contraction.
Fainting (Syncope) Symptoms, Causes, Treatment, and Prevention
Fainting, also referred to as blacking out, syncope, or temporary loss of consciousness has many causes. Often a person will have signs or symptoms prior to the fainting episode. Diagnosis and treatment depends upon the cause of the fainting or syncope episode.
Blood Clots (In the Leg)
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for causes of blood clots include high blood pressure and cholesterol, diabetes, smoking, and family history. Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
Medical shock is a life-threatening medical condition. There are several types of medical shock, including: septic shock, anaphylactic shock, cardiogenic shock, hypovolemic shock, and neurogenic shock. Causes of shock include: heart attack, heart failure, heavy bleeding (internal and external), infection, anaphylaxis, spinal cord injury, severe burns, chronic vomiting or diarrhea. Low blood pressure is the key sign of sock. Treatment is dependant upon the type of shock.
Pulmonary Embolism (Blood Clot in the Lung)
A pulmonary embolism (PE) occurs when a piece of a blood clot from deep vein thrombosis (DVT) breaks off and travels to an artery in the lung where it blocks the artery and damages the lung. The most common symptoms of a pulmonary embolism are shortness of breath, chest pain, and a rapid heart rate. Causes of pulmonary embolism include prolonged immobilization, certain medications, smoking, cancer, pregnancy, and surgery. Pulmonary embolism can cause death if not treated promptly.
Fatigue can be described in various ways. Sometimes fatigue is described as feeling a lack of energy and motivation (both mental and physical). The causes of fatigue are generally related to a variety of conditions or diseases, for example, anemia, mono, medications, sleep problems, cancer, anxiety, heart disease, and drug abuse.Treatment of fatigue is generally directed toward the condition or disease that is causing the fatigue.
Low Blood Sugar (Hypoglycemia)
Low blood sugar, or hypoglycemia, is a syndrome in which a person's blood sugar is dangerously low. People with type 1 and type 2 diabetes are at risk for this condition. There are other diseases that can cause a person's blood sugar levels to go too low, for example, pancreatitis, Cushing's syndrome, and pancreatic cancer. Symptoms and signs that your blood sugar levels are too low include palpitations, trembling, intense hunger, sweating, nervousness, and weakness. If your blood sugars become too low, use these nearby as a quick treatment table sugar, soda, juice, and glucose tablets.
A heart attack happens when a blood clot completely obstructs a coronary artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical instability of the heart.
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. Symptoms of dehydration include headache, lightheadedness, constipation, and bad breath. Treatment for dehydration is to replace lost fluids and electrolytes.
High Blood Pressure (Hypertension) Signs, Causes, Diet, and Treatment
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms. Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure. The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater. If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.REFERENCE: CDC. High Blood Pressure. Updated: Nov 13, 2017.
Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include: Smoking High blood pressure High cholesterol Diabetes Family history Obesity Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.
Chest pain is a common complaint by a patient in the ER. Causes of chest pain include broken or bruised ribs, pleurisy, pneumothorax, shingles, pneumonia, pulmonary embolism, angina, heart attack, costochondritis, pericarditis, aorta or aortic dissection, and reflux esophagitis. Diagnosis and treatment of chest pain depends upon the cause and clinical presentation of the patient's chest pain.
Low Potassium (Hypokalemia)
Potassium is an essential electrolyte necessary for cell function. Low potassium (hypokalemia) may be caused by diarrhea, vomiting, ileostomy, colon polyps, laxative use, diuretics, elevated corticosteroid levels, renal artery stenosis, and renal tubular acidosis, or other medications. Symptoms of low potassium include weakness, aches, and cramps of the muscles. Treatment is dependent upon the cause of the low potassium (hypokalemia).
Premenstrual Dysphoric Disorder (PMDD)
Premenstrual dysphoric disorder (PMDD) is considered a severe form of premenstrual syndrome (PMS). PMDD has also been referred to as late luteal phase dysphoric disorder. The cause of PMDD is unknown. Some of the common symptoms of PMDD (not an inclusive list) include mood swings, bloating, fatigue, headache, irritability, headache, breast tenderness, acne, and hot flashes. Treatment for PMDD is with medication to treat the symptoms of PMDD.
Angina (Symptoms, Causes, Types, Diagnosis, and Treatment)
Angina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.
Pericarditis (Symptoms, ECG, Types, Causes, Treatment)
Pericarditis is the inflammation of the pericardial sac that surrounds the heart. The causes of pericarditis include injury from heart attack, heart surgery, trauma; viral or fungal infection, HIV, tumors, mixed connective tissue disease, metabolic disease, medication reactions, or idiopathic. Treatment for pericarditis is generally medication, however, sometimes surgery is necessary.
Dilated Cardiomyopathy is a condition where the heart's ability to pump blood is decreased because the heart's main pumping chamber is enlarged and weakened. Symptoms of dilated cardiomyopathy include chest pain, heart failure, swelling of the lower extremities, fatigue, weight gain, fainting, palpitations, dizziness and blood clots.
Stress and Heart Disease
The connection between stress and heart disease is not clear. Stress itself may be a risk factor, or high levels of stress may make risk factors for heart disease worse. The warning signs of stress can be physical, mental, emotional, or behavioral. Reducing stressors in an individuals life not only can lead to a more productive life, but may also decrease the risk for heart disease and causes of heart disease.
Mitral Valve Prolapse (Syndrome, Symptoms, Causes, Treatment, Surgery)
Mitral valve prolapse (MVP), also called "click murmur syndrome" and "Barlow's syndrome," is the most common type of heart valve abnormality. Usually, people with mitral valve prolapse have no signs and symptoms; however, if the prolapsed valve is severe, symptoms may appear. When symptoms of severe mitral valve prolapse do appear, they may include, fatigue, palpitations, chest pain, anxiety, migraine headaches, and pulmonary edema. Echocardiography is the most useful test for mitral valve prolapse. Most people with mitral valve need no treatment. However, if the valve prolapse is severe, treatment medications or surgery may be necessary to repair the heart valve.
Heart failure (congestive) is caused by many conditions including coronary artery disease, heart attack, cardiomyopathy, and conditions that overwork the heart. Symptoms of heart failure include congested lungs, fluid and water retention, dizziness, fatigue and weakness, and rapid or irregular heartbeats. There are two types of congestive heart failure, systolic or left-sided heart failure; and diastolic or right-sided heart failure. Treatment, prognosis, and life-expectancy for a person with congestive heart failure depends upon the stage of the disease.
Hemochromatosis (Iron Overload)
Hereditary hemochromatosis (iron overload) is an inherited disorder in which there is excessive accumulation of iron in the body. Individuals may have no symptoms or signs, or they can have severe symptoms and signs of iron overload. The most effective treatment for hemochromatosis is therapeutic phlebotomy.
Premature Ventricular Contractions (PVCs, PVC)
Premature ventricular contractions (PVCs, PVC) are premature heartbeats originating from the ventricles of the heart. PVCs are premature because they occur before the regular heartbeat. There are many causes of premature ventricular contractions to include: heart attack, high blood pressure, congestive heart failure, mitral valve prolapse, hypokalemia, hypoxia, medications, excess caffeine, drug abuse, and myocarditis.
Atrial Flutter (Symptoms, Causes, ECG, and Treatments)
Atrial flutter is a problem with the atria of the heart. In atrial flutter the atria of the heart rapidly and repeatedly beat due to an anomaly in the electrical system of the heart. It is a type of arrhythmia and can be dangerous because complications can develop easily. Signs and symptoms of atrial flutter include near fainting, palpitations, mild shortness of breath, and fatigue. While the exact cause of atrial flutter is not clearly understood, it's most likely related to your health, what medical conditions you certainly have, poor diet, lack of exercise, and drinking too much alcohol. Atrial flutter is diagnosed by physical examination, medical history, and a sawtooth ECG wave pattern.
Marfan syndrome is hereditary (genetic) condition affecting connective tissue. A person with Marfan syndrome may exhibit the following symptoms and characteristics: Dislocation of one or both lenses of the eye A protruding or indented breastbone Scoliosis Flat feet Aortic dilatation Dural ectasia (a problem with the sac surrounding the spinal cord) Stretch marks Hernia Collapsed lung Though there is no cure for Marfan syndrome, there are treatments that can minimize and sometimes prevent some complications.
Emphysema is a COPD (chronic obstructive pulmonary disease) that often occurs with other obstructive pulmonary problems and chronic bronchitis. Causes of emphysema include chronic cigarette smoking, exposure to secondhand smoke, air pollution, and in the underdeveloped parts of the world. Symptoms of emphysema include chronic cough, chest discomfort, breathlessness, and wheezing. Treatments include medication and lifestyle changes.
Aortic Valve Stenosis (Symptoms, Causes, Surgery)
Aortic valve stenosis is an abnormal narrowing of the aortic valve of the heart. The causes of aortic stenosis are wear and tear of the valve in the elderly, congenital, or scarring or scarring of the aortic valve from rheumatic fever. Symptoms include angina, fainting, and shortness of breath. Treatment is dependant upon the severity of the condition.
Schistosomiasis (snail fever), a disease caused by parasites, causes a variety of symptoms and signs, such as cough, rash and bloody diarrhea. Praziquantel is used in the treatment of schistosomiasis.
Chagas Disease (American Trypanosomiasis or Kissing Bug Disease)
Chagas disease is an infection caused by the T. cruzi parasite. Symptoms of Chagas disease include rash, swollen lymph nodes, fever, fatigue, nausea, vomiting, and the Romaña sign. An ELISA test is used to diagnose Chagas disease. Treatment depends upon the phase of the disease and the patient's age.
Heart Murmur in Newborns, Children, and Adults
A heart murmur is a heart problem that can occur, for example, during pregnancy or exercise, or it can be a symptom of serious heart condition, for example, congenital heart defects or heart valve disease. A heart murmur makes a whooshing or swishing sound. Symptoms of a heart murmur include swelling of the legs or feet, dizzy or lightheaded, black outs, chest pain, rapid heart rate (palpitations), difficulty doing normal daily activities, fatigue, and a bluish tinge on the skin, lips, and fingernails. Treatment for heart murmurs in infants, children, and adults depend on the cause. Some heart murmurs can be harmless while some are serious and life threatening.
Erectile Dysfunction (ED, Impotence)
Erectile dysfunction (ED, impotence) is the failure to achieve or maintain an erection. There are many potential underlying causes of erectile dysfunction, including stress and emotional problems, brain dysfunction, problems with blood supply to the penis, and structural problems with the penis. Erectile dysfunction is diagnosed by taking the patient's history and physical exam. Blood tests measuring kidney function and blood sugar, cholesterol, hormone, and prostate-specific antigen (PSA) levels may be ordered. Urinalysis, ultrasound, and other more sophisticated tests may be required. The treatment of erectile dysfunction depends on the underlying cause. Medications, penile injections, penile implants, and vacuum devices may be used. Treatment for erectile dysfunction is usually successful. The patient should manage heart disease risk factors (high blood pressure, high cholesterol, diabetes) as they are related to erectile dysfunction risk.
Pheochromocytoma is a tumor of the adrenal gland. Pheochromocytomas are quite rare and the vast majority of them are entirely benign. Only very rarely is a pheochromocytoma malignant. People with pheochromocytoma usually show these three symptoms: headache, sweating, and heart palpitations (a fast heart beat) in association with markedly elevated blood pressure (hypertension). Other conditions that may accompany these classic symptoms are as follows: anxiety, nausea, tremors, weakness, abdominal pain, and weight loss.
Asthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.
Cocaine and Crack Abuse
Cocaine is an addictive stimulant that is smoked, snorted, and injected. Crack is cocaine that comes in a rock crystal that is heated to form vapors, which are then smoked. Cocaine has various effects on the body, including dilating pupils, constricting blood vessels, increasing body temperature, heart rate, and blood pressure.
Atrial Flutter vs. Atrial Fibrillation (What Are the Differences?)
Atrial flutter and atrial fibrillation (AFib) are two types of a heart problem called atrial tachycardia. Both of these conditions involve the heart's electrical activity, but they are not the same disease. Both diseases are serious and need medical treatment. Common symptoms of these diseases are similar and include: Fatigue Blurry vision Lightheadedness Palpitations Feeling like you may faint Serious symptoms of both conditions are similar and include: Fainting Sweating Severe shortness of breath Chest pain Atrial flutter and AFib are heart conditions that require medical diagnosis (ECG) and treatment by a doctor or other medical health-care professional.
Heart Valve Disease
Heart valve disease occurs when the heart valves do not work the way they should. Symptoms of valve disease include shortness of breath, weakness or dizziness, discomfort in your chest, palpitations, swelling of your ankles, feet or abdomen, and rapid weight gain.
Abnormal Heart Rhythms (Heart Rhythm Disorders)
Heart rhythm disorders vary from minor palpitations, premature atrial contractions (PACs), premature ventricular contractions (PVCs), sinus tachycardia, and sinus brachycardia, to abnormal heart rhythms such as tachycardia, ventricular fibrillation, ventricular flutter, atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia (PSVT), Wolf-Parkinson-White syndrome, brachycardia, or heart blocks. Treatment is dependent upon the type of heart rhythm disorder.
Paroxysmal Supraventricular Tachycardia (PSVT)
Paroxysmal supraventricular tachycardia (PSVT) is an abnormal conduction of electricity in particular areas of the heart. PSVT was referred to at one time as paroxysmal atrial tachycardia or PAT, however, the term PAT is reserved for as specific heart condition. Symptoms of PSVT include weakness, shortness of breath, chest pressure, lightheadedness, and palpitations. PSVT is treated with medications or procedures that return the heart to its normal electrical pattern.
Smoking (How to Quit Smoking)
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
Atrial Fibrillation vs. Ventricular Fibrillation (AFib vs VFib Symptoms, ECG Strips)
Atrial fibrillation (AF or AFib) is an abnormality in the heart rhythm which involves irregular and often rapid beating of the heart. Symptoms may include heart palpitations, dizziness, fainting, fatigue, shortness of breath, and chest pain. Atrial fibrillation treatment may include medication or procedures like cardioversion or ablation to normalize the heart rate. Atrial fibrillation (AFib) and ventricular fibrillation (VFib) are problems with the heart that cause abnormal heart rhythms. Causes of these heart conditions include, heart disease, drugs and medications, excessive alcohol consumption, high cholesterol, advancing age, a diet that contains high levels of animal meat (fat), high blood pressure, stress, stimulants like caffeine, nicotine. Ventricular fibrillation is the more serious of the conditions because if it isn't treated immediately the person will likely die. Symptoms of AFib are confusion, anxiety, fatigue, a fluttering in the chest, and the feeling that you may pass out or faint. Atrial fibrillation is treated with medications, cardioversion therapy, and surgery. If a person with ventricular fibrillation does not seek medical help immediately they will mostly likely suffer from sudden cardiac arrest or sudden death.
Atrial Fibrillation (AFib, AF)
Atrial fibrillation (AF or AFib) is an abnormality in the heart rhythm, which involves irregular and often rapid beating of the heart. Symptoms may include heart palpitations, dizziness, fainting, fatigue, shortness of breath, and chest pain. Atrial fibrillation treatment may include medication or procedures like cardioversion or ablation to normalize the heart rate.
Atrial Fibrillation Symptoms (AFib Warning Signs)
Atrial fibrillation or AFib is a type of hear rhythm abnormality. Early warning signs and symptoms of atrial fibrillation include chest pain, palpitations, shortness of breath, and lightheadedness. Treatment for atrial fibrillation includes medical procedures, surgery, and medication.
Atrial Fibrillation (AFib) Treatment Drugs
Atrial fibrillation (AFib) is a heart rhythm disorder that causes irregular and often rapid heartbeat. The medications to treat AFib include beta-blockers, blood thinners, and heart rhythm drugs. Atrial fibrillation drugs can cause serious side effects like seizures, vision changes, shortness of breath, fainting, other abnormal heart rhythms, excessive bleeding while coughing or vomiting, blood in the stool, and bleeding into the brain.
Panic attacks are sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. A person experiencing a panic attack may believe that he or she is having a heart attack or that death is imminent. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms: racing heartbeat, faintness, dizziness, numbness or tingling in the hands and fingers, chills, chest pains, difficulty breathing, and a feeling of loss or control. There are several treatments for panic attacks.
Stress Management Techniques
Stress may be considered as any physical, chemical, or emotional factor that causes bodily or mental unrest and that may be a factor in disease causation. An important goal for those under stress is the management of stress in our lives. Elimination of stress is unrealistic, since stress is a part of normal life. We can however, learn to manage stress through techniques such as exercise, relaxation, meditation, time management, and support systems so that we have control over our stress and its effects on our physical and mental health.
Scar formation is a natural part of the healing process after injury. The depth and size of the wound incision and the location of the injury impact the scar's characteristics, but your age, heredity and even sex or ethnicity will affect how your skin reacts.
Is Lyme Disease Contagious?
Lyme disease may be transmitted to humans via the bite of an infected tick. The bacterium Borrelia burgdorferi causes the disease and is passed to humans during a tick's blood meal. Lyme disease does not spread from person to person.
Hypertrophic cardiomyopathy (HCM) affects many people today. Many people with HCM have no symptoms or only minor symptoms, and live a normal life. Other people develop symptoms, which progress and worsen as heart function worsens.
Nicotine is delivered to the brain through smoking, chewing, or sniffing tobacco. Nicotine is an addictive agent. Common names for nicotine products include smokes, cigs, butts, chew, dip, spit, or snuff. Habitual nicotine use leads to many debilitating medical conditions.
Wolff-Parkinson-White syndrome is a condition in which abnormal electrical pathways in the heart cause arrhythmias. Symptoms of Wolff-Parkinson-White syndrome include: tachycardia, dizziness, palpitations, fainting, and shortness of breath. Wolff-Parkinson-White syndrome is a common cause of paroxysmal supraventricular tachycardia. Wolff-Parkinson-White syndrome is caused by mutations in the PRKAG2 gene.
Smoking and Heart Disease
Smoking increases the risk of heart disease in women and men. Nicotine in cigarettes decrease oxygen to the heart, increases blood pressure, blood clots, and damages coronary arteries. Learn how to quit smoking today, to prolong your life.
Restrictive cardiomyopathy, the rarest form of cardiomyopathy, is a condition in which the walls of the lower chambers of the heart (the ventricles) are abnormally rigid and lack the flexibility to expand as the ventricles fill with blood. The pumping or systolic function of the ventricle may be normal but the diastolic function (the ability of the heart to fill with blood) is abnormal. Therefore, it is harder for the ventricles to fill with blood, and with time, the heart loses the ability to pump blood properly, leading to heart failure.
Regular physical activity can reduce the risk of disease. Regular exercise can also reduce the symptoms of stress and anxiety. There are fitness programs that fit any age or lifestyle.
