Medications and procedures such as cardioversion can restore abnormal heart rhythms caused by atrial fibrillation. There are also many anti-arrhythmia medications with variable levels of effectiveness. Beta-blockers are often used to slow the heart rate down, which is an important aspect of treatmen
It is a highly effective treatment for atrial fibrillation. The name is used loosely nowadays. A full Cox maze procedure is about 95% effective. The more commonly performed left atrial surgical pulmonary vein interruptions are much less effective. It is, of course, highly invasive.
Long QT syndrome is a congenital abnormality of the ability of the heart to conduct electricity properly. Long QT refers to its manifestation on an electrocardiogram. It can cause recurrent bouts of passing out and ultimately sudden death. It is not common.
During atrial fibrillation the blood is stagnant in the atria (the upper chamber of the heart), where it can clot. The clot can travel to other parts of the body including the brain. Atrial fibrillation is the most common cause of stroke.
People with atrial fibrillation (A-Fib) are given blood thinners (anticoagulants) because they prevent blood clots that tend to form in the atria. This helps to prevent strokes. Coumadin (warfarin) is the most common anticoagulant.
There is always a risk of stroke with atrial fibrillation (AF). It is highest immediately after cardioversion. However, cardioversion without other interventions is considered safe when AF has been there for less than 24 hours.
Untreated atrial fibrillation with fast rates can weaken the heart, sometimes permanently (most commonly until treated). The left atrium both grows and is more prone to cause atrial fibrillation the longer it is in atrial fibrillation.
The cornerstone of therapy is Coumadin- until recently, the only available oral anticoagulant. Pradaxa is a new oral anticoagulant. For controlling rates, beta-blockers and calcium blockers are used. For trying to minimize atrial fibrillation, antiarrhythmics such as amiodarone, dronedarone, dofe...
