Atrial fibrillation and flutter are abnormal heart rhythms in which the atria, or upper chambers of the heart, are out of sync with the ventricles, or lower chambers of the heart. In atrial fibrillation, the atria"quiver" chaotically and the ventr...

Atrial fibrillation/flutter is a heart rhythm disorder(arrhythmia). It usually involves a rapid heart rate, in which the upper heart chambers(atria) are stimulated to contract in a very disorganized and abnormal manner.Arrhythmias are caused by a ...

Detailed information on atrial fibrillation, a type of arrhythmia, including symptoms and diagnostic information
|
|
Electrical system problems of the heart may make the atria beat faster than normal. If the atria beat quickly, but still evenly, it is called atrial flutter. If the atria beat very quickly and unevenly, it is called atrial fibrillation.
|
|
Atrial fibrillation, an irregular, fluttering heart rhythm, can cause dangerous clots. It can often be treated with medication, but if this approach is not effective, surgery may be necessary.
|
|
Atrial fibrillation can occur with no symptoms, but the resulting risk of stroke is quite serious.
|
|
Pulse pressure is the difference between the high and low blood pressure measurements. A high pulse pressue (larger than 40) may lead to the development of atrial fibrillation, an irregular heart rhythm.
|
|
Surgeons have been trying to correct atrial fibrillation with operations that are less complex and less invasive, but so far there is not enough evidence to confirm their effectiveness.

I am 86 years old and have been taking Fosamax to strengthen my bones for nearly 10 years. A few months ago, I suddenly fainted and was later diagnosed with atrial fibrillation. Did that happen because I was taking Fosamax?

A Harvard Medical School physician answers your question about the side effects of medication for atrial fibrillation, and potential alternatives.

|
Some parameters of using rhythm control for atrial fibrillation.Although controlling the heart's rate is a good first step for treating atrial fibrillation, some people benefit from restoring a normal rhythm.
|
|
Five years ago, my wife was diagnosed with atrial fibrillation. Her rhythm returned to normal with intravenous medication. She has been taking warfarin since this started, and her cardiologist wants her to take it indefinitely. Does she need to?
|
|
Atrial fibrillation can increase the risk of heart failure or stroke in those over 60. Traditionally this condition has been treated with medication, but there are several alternatives that may be better for some patients.
|
|
Cardiologists found a case where too much talking was a trigger for atrial fibrillation.
|
|
Catheter ablation is showing promise as a nonsurgical treatment for curing atrial fibrillation, rather than just managing it.

 |
The endocardium is the inner lining of the heart muscle, which also covers the heart valves. When the endocardium becomes damaged, bacteria from the blood stream can become lodged on the heart valves or heart lining.
|
|
|
Endocarditis is inflammation of the inside lining of the heart chambers and heart valves(endocardium).
|
|
Endocarditis is an infection of the endocardium, the inner lining of the heart muscle and its four valves(tricuspid, pulmonary, mitral, and aortic). Abnormal or damaged endocardium is more likely to become infected when bacteria enter the bloodstr...

Mitral stenosis is a heart valve disorder that involves the mitral valve. This valve separates the upper and lower chambers on the left side of the heart.
|
|
Valve disease occurs when a valve doesn't open or close the way it should. If a valve doesn't open all the way, the heart has to push blood through a smaller opening. If the valve doesn't close tightly, some blood will leak backward.
|
|
Mitral stenosis means the mitral valve stiffens and doesn't open right. Blood must move through a smaller opening. In severe cases, fluid can build up in the lungs, leading to coughing and breathing problems.
|
|
The term stenosis means an abnormal narrowing of an opening. Mitral valve stenosis refers to a condition in the heart in which one of the valve openings has become narrow and restricts the flow of blood from the upper left chamber(left atrium) to ...

Thrombocytosis is a blood disorder in which the body produces a surplus of platelets(thrombocytes).Thrombocytosis is an abnormally increased number of platelets in the blood. Platelets are blood cells that stick together, helping blood to clot.
