What is Paroxysmal atrial fibrillation?

1 doctor answer
Dr. Stuart Higano
36 years experience in Cardiology
Irregular pulse: Paroxysmal atrial fibrillation is an abnormal heart rhythm that is intermittent (or paroxysmal), arising from the upper chambers of the heart (or atria), and is very chaotic, or irregular (fibrillating). It can cause problems because it usually drives the heart rate up too fast (giving symptoms and eventually weakening the heart) and can increase the risk of stroke. Causes of PAF are multiple.
