What is Atrial Fibrillation and What Causes It?

What Is Atrial Fibrillation (AF or A-Fib)?

Atrial fibrillation (AF or A-fib) is the most common cardiac arrhythmia (heart rhythm disorder). It can also be identified clinically when the pulse is taken. Atrial Fibrillation can be confirmed using an electrocardiogram (ECG or EKG) as this can demonstrate the absence of P waves together with an irregular ventricular rate.

What Causes Atrial Fibrillation?

There may be no obvious symptoms, but the condition is often associated with palpitations, fainting, chest pain, and even congestive heart failure. However, atrial fibrillation can in some people be otherwise idiopathic or brought on by benign conditions.
