Abnormal Heart Rhythms (Heart Rhythm Disorders)Read the Abnormal Heart Rhythms (Heart Rhythm Disorders) article » How does the heart work?The heart is a two stage electric pump whose job it is to circulate blood through the body. There is a group of cells that serve as an automatic pacemaker located in the atrium that generates an electrical current that spreads to the heart muscle cells to generate a coordinated squeeze, so that the pump can function. The heart has four chambers, the right and left atria (singular= atrium) and the right and left ventricles. The right side of the heart pumps blood to the lungs while the left side pumps it to the rest of the body. Blood from the body is collected in the right atrium and is pushed into the right ventricle with a small beat of the upper chamber of the heart. The right ventricle then pumps the blood to the lungs to pick up oxygen. They oxygen-rich blood returns to the left atrium where the small atrial beat pushes it to the left ventricle. The left ventricle is much thicker than the right because it needs to be strong enough to send blood to the entire body. There are special cells in the right atrium called the sino-atrial node (SA node) that generate the first electrical impulse, allowing the heart to beat in a coordinated way. The SA node is considered the "natural pacemaker" of the heart. This pacemaker function begins the electrical impulse which follows pathways in the atrial walls, almost like wiring, to a junction box between the atrium and ventricle called the atrio-ventricular node (AV node). This electric signal causes muscle cells in both atria to contract at once. At the AV node, the electric signal waits for a very short time, usually one to two tenths of a second, to allow blood pumped from the atria to fill up the ventricles. The signal then passes through electric bundles in the ventricle walls to allow these chambers to contract, again in a coordinated way, and pump blood to the lungs and body. The SA node generates an e...

By positioning leads (electrical sensing devices) on the body in standardized locations, information about many heart conditions can be learned by looking for characteristic patterns on the EKG. How is an ECG (EKG) performed?EKG leads are attached to the body while the patient lies flat on a bed or table. Leads are attached to each extremity (four total) and to six pre-defined positions on the front of the chest. A small amount of gel is applied to the skin, which allows the electrical impulses of the heart to be more easily transmitted to the EKG leads. The leads are attached by small suction cups, Velcro straps, or by small adhesive patches attached loosely to the skin. The test takes about five minutes and is painless. In some insta...

Low Blood Pressure
- 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, or even 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.
-
Congestive Heart Failure
- Congestive heart failure (CHF) is a condition in which the heart's function as a pump is inadequate to meet the body's needs. A poor blood supply resulting from congestive heart failure may cause the body's organ systems to fail, leading to a weakened heart muscle and fluid accumulation in the lungs and body tissue. There are many diseases that can impair pumping efficiency and symptoms of congestive heart failure including fatigue, diminished exercise capacity, shortness of breath, and swelling. Treatments include lifestyle modifications, medications, heart transplant, and therapy.
-
High Blood Pressure
- High blood pressure, also known as hypertension, is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
-
Dizziness
- Dizziness is a symptom that is often applies to a variety of sensations including lightheadedness and vertigo. Causes of dizziness include low blood pressure, heart problems, anemia, dehydration, and more. Treatment of dizziness depends on the cause.
-
Stroke
- A stroke results from impaired oxygen delivery to brain cells via the bloodstream. A stroke is also referred to as a CVA, or cerebrovascular incident. Symptoms of stroke include: sudden numbness or weakness of the face, arm or leg. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, or loss of balance, and/or sudden severe headache with no known cause. A TIA, or transient ischemic attack is a short-lived temporary impairment of the brain caused by loss of blood supply. Stroke is a medical emergency.
-
Pulmonary Embolism (Blood Clot in the Lung)
- A pulmonary embolism 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.
-
Fainting (Syncope)
- 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.
-
Palpitations
- Palpitations are unpleasant sensations of irregular and/or forceful beating of the heart. Palpitations can be relieved in many patients by stress reduction, stopping cigarettes, and reduction of caffeine and alcohol.
-
Heart Attack
- 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.
-
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 dependant upon the cause of the low potassium (hypokalemia).
-
Premature Ventricular Contractions (PVCs)
- Premature ventricular contractions (PVCs) 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 Fibrillation
- Atrial fibrillation is an abnormality in the heart rhythm which involves irregular and often rapid beating of the heart.
-
Heart Disease
- Heart disease (coronary artery disease) is caused by a buildup of cholesterol deposits in the coronary arteries. Risk factors for heart disease include smoking, high blood pressure, heredity, diabetes, peripheral artery disease, and obesity. Symptoms include chest pain and shortness of breath. There are a variety of tests used to diagnose coronary artery disease. Treatment includes life-style changes, medications, procedures, or surgery.
-
Pulmonary Edema
- Pulmonary edema (swelling or fluid in the lungs) can either be caused by cardiogenic causes (congestive heart failure, heart attacks, abnormal heart valves) or noncardiogenic causes such as ARDS, kidney failure, high altitude, pneumothorax, pleural effusion, aspirin overdose, pulmonary embolism, and infections. The treatment of pulmonary edema depends on the cause of the condition.
-
Orthostatic Hypotension
- Orthostatic hypotension symptoms include lightheadedness, weakness, blurred vision, and syncope or passing out. Causes of orthostatic hypotension include dehydration, anemia, medication, blood loss, low blood pressure, heat related illnesses and more. Treatment of orthostatic hypotension depends on the underlying cause.
-
Hypercalcemia (Elevated Calcium Levels)
- Hypercalcemia is a condition in which calcium levels in the blood are elevated. Hypercalcemia is associated with other conditions such as hyperparathyroidism, lung cancer, breast cancer, kidney failure, and elevated levels of vitamin D. Symptoms of hypercalcemia include constipation, nausea, abdominal pain, kidney stones, to name a few. Treatment depends on the cause of hypercalcemia.
-
Wolff-Parkinson-White Syndrome
- 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.
-
Sudden Cardiac Arrest
- Sudden cardiac arrest is an unexpected, sudden death caused by sudden cardiac arrest (loss of heart function). Causes and risk factors of sudden cardiac arrest include (not inclusive): abnormal heart rhythms (arrhythmias), previous heart attack, coronary artery disease, smoking, high cholesterol, Wolff-Parkinson-White Syndrome, ventricular tachycardia or ventricular fibrillation after a heart attack, congenital heart defects, history of fainting, and heart failure, obesity, diabetes, and drug abuse. Treatment of sudden cardiac arrest is an emergency, and action must be taken immediately.
-
Coma
- Coma is the inability to waken or react to the surrounding environment. The Glasgow Coma Scale is frequently used to measure the depth of coma. Causes of coma include trauma, bleeding, edema, lack of oxygen, poisoning, or hypoglycemia. Prognosis for a patient in a coma depends on the cause of the coma.
-
Hypothermia
- Hypothermia is having a body core temperature of less than 35 C or 95 F. Most causes of hypothermia are preventable. Risk factors for hypothermia include age, mental status, medical conditions, and medications. Symptoms of hypothermia generally depend upon the severity of the condition. Treatment depends upon the severity of hypothermia. If not treated early, hypothermia can lead to cardiac arrest, coma, or death.
-
How the Heart Works
- 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.
-
Shock (Medical)
- Medical shock is a life-threatening medical condition. There are several types of medical shock, 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.
-
Mitochondrial Disease
- Learn about mitochondrial disease, genetic disease in which include a group of neuromuscular diseases that are caused by damage to the mitochondria Common mitochondrial myopathies include Kearns–Sayre syndrome, myoclonus epilepsy, and mitochondrial encephalomyopathy. Symptoms of mitochondrial disease include heart failure, exercise intolerance, dementia, muscle weakness, movement disorders, deafness, blindness, stroke-like episodes, and more. There is no specific treatment for mitochondrial disease.
-
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.
-
Alpha Thalassemia
- Alpha thalassemia is a disorder in which the alpha globin protein is underproduced. There are two pairs of genes that carry the code for the alpha chains of hemoglobin. When one gene is impaired, that person is in a carrier state and suffers no medical problems. When four genes are impaired, the production of fetal and adult hemoglobin is prevented, resulting in hydrops fetalis and leading to death before birth.
-
Sleepwalking
- Sleepwalking is a condition in which an individual walks or does other activities while asleep. Factors associated with sleepwalking include genetic, environmental, and physiological. Episodes of sleepwalking may include quiet walking to agitated running. Conditions that may have similar symptoms of sleepwalking, but are not include night terrors, confusional arousals, and nocturnal seizures. Treatment of sleepwalking generally include preventative measures. Medication may be prescribed if necessary.
-
Heart Failure
- Heart failure 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.
-
Chagas 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 Attacks in Women
- Heart disease, particularly coronary artery disease is the leading cause of heart attacks. Women are more likely to die from a heart attack than men. High cholesterol, high blood pressure, obesity, and high triglycerides are contributors to heart disease. Some of the common symptoms of a heart attack in women include chest pain, shortness of breath, nausea, feeling faint or woozy, and more. Heart disease can be prevented by lifestyle changes and controlling high blood pressure, cholesterol, weight, and diseases such as diabetes.
