Atrial fibrillation (AFib) is a heart rhythm abnormality caused by a problem with your heart's electrical system. Normally, your heart's electricity flows from the top chambers (atria) to the bottom chambers (ventricles), causing a normal contraction. In atrial fibrillation, the electrical flow ...
Valvular atrial fibrillation This type affects people who have an artificial heart valve or valve disease such as valvular stenosis (when one of your heart valves stiffens) or regurgitation (when a valve isn’t closing properly, which lets some blood flow the wrong way). Your chance of getting...

The treatment option for atrial fibrillation includes medications like blood thinners and beta-blockers. However, various procedures can be performed to ...
Most commonly, atrial fibrillation occurs as a result of some other cardiac condition (secondary atrial fibrillation). Heart valve disease:This condition results from developmental abnormalities people are born with or can be caused by infection or degeneration/calcification of valves with age. ...
Atrial fibrillation is a supraventricular tachyarrhythmia and the most common kind. It is caused by rapid, uncontrolled atrial contractions and uncoordinated ventricular responses.
