Atrial FibrillationRead the Atrial Fibrillation article » What is atrial fibrillation?Atrial fibrillation (AF) is the most common, abnormal rhythm of the heart. The heart contracts (beats) and pumps blood with a regular rhythm, for example,
at a rate of 60 beats per minute there is a beat every second. The heart may
beat faster or slower with a shorter or longer interval between beats, but at
any one rate the interval between beats is constant. This regular rhythm occurs
as a result of regular electrical discharges (currents) that travel through the
heart and cause the muscle of the heart to contract. In atrial fibrillation, the electrical
discharges are irregular and rapid and, as a result, the heart beats irregularly
and, usually, rapidly.
What causes atrial fibrillation?Normal function of the heart The heart has four chambers. The upper two chambers are the atria, and the lower two chambers are the ventricles. Blood returning to the heart from the body in the superior and inferior vena cava contains low levels of oxygen and high levels of carbon dioxide. This blood flows into the right atrium and then into the adjacent right ventricle. After the ventricle fills, contraction of the right atrium pumps additional blood into the right ventricle. The right ventricle then contracts and pumps the blood to the lungs where the blood takes up oxygen and gives off carbon dioxide. The blood then flows from the lungs to the left atrium and into the adjacent left ventricle. Contraction of the left atrium pumps additional blood into the left ventricle. The left ventricle then contracts and pumps the blood to the rest of the body. The heartbeat (pulse) that we feel is caused by the contraction of the ventricles. The ventricles must deliver enough blood to the ...

Coronary atherosclerosis is the major cause of heart attacks. Heart attacks are the major cause of sudden unexpected death among otherwise healthy adults in the prime of their lives. Heart attacks are also a significant cause of heart failure (due to weakened heart muscle) in this country. Heart failure considerably decreases a person's longevity and quality of life. In dollar terms, coronary heart disease is costly. The total cost of coronary artery bypass surgery, coronary angioplasty and stenting, medications, and hospitalizations exceeds 50 billion dollars annually. Coronary atherosclerosis, and hence heart attacks, are preventable. A person can significantly lower his or her risk of heart attack by lowering high blood pressure, controlling diabetes, stopping cigarett...

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.
-
Blood Clots
- 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 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.
-
Arrhythmia
- 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 prmature contraction.
-
Hyperthyroidism
- Hyperthyroidism is an excess of thyroid hormone resulting from an overactive thyroid gland. Symptoms can include increased heart rate, weight loss, depression, and cognitive slowing. Treatment is by medication, the use of radioactive iodine, thyroid surgery, or reducing the dose of thyroid hormone.
-
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.
-
Chronic Obstructive Pulmonary Disease
- COPD (chronic obstructive pulmonary disease) is a disorder that persistently obstructs bronchial airflow. COPD mainly involves three related conditions, chronic bronchitis, chronic asthma, and emphysema. Symptoms of COPD include chronic cough, shortness of breath, frequent respiratory infections, wheezing, morning headaches, and pulmonary hypertension. Treatment of COPD is focused on the related condition(s).
-
Mitral Valve Prolapse (MVP)
- Mitral valve prolapse (MVP) is also also known as "click murmur syndrome" and "Barlow's syndrome." Mitral valve prolapse is the most common heart valve abnormality. Signs and symptoms of mitral valve prolapse include: fatigue, palpitations, chest pain, anxiety, and migraine headaches. Echocardiography is the most useful test for mitral valve prolapse. Most patients do not need any treatment, however, patients with severe prolapse may need treatment.
-
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-White-Parkinson syndrome, brachycardia, or heart blocks. Treatment is dependant upon the type of heart rhythm disorder.
-
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.
-
Pericarditis
- 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.
-
Rheumatic Fever
- Rheumatic fever is a disease that sometimes occurs after a group A streptococcal infection of the throat. Symptoms and signs include carditis, polyarthritis, Aschoff bodies, rash, Sydenham's chorea, and fever. Treatment for rheumatic fever involves eliminating the bacteria with penicillin, erythromycin, or azithromycin. Further treatment focuses on alleviating the symptoms brought on by the body's immunologic response to the bacteria.
-
Transient Ischemic Attack (TIA, Mini-Stroke)
- When a portion of the brain loses blood supply, through a blood clot or embolus, a transient ischemic attack (TIA, mini-stroke) may occur. If the symptoms do not resolve, a stroke most likely has occurred. Symptoms of TIA include: confusion, weakness, lethargy, and loss of function to one side of the body. Risk factors for TIA include vascular disease, smoking, high blood pressure, high cholesterol, and diabetes. Treatment depends upon the severity of the TIA, and whether it resolves.
