what is the difference between atrial fibrillation and ventricular fibrillation?

It depends: Ventricular fibrillation is from the bottom chamber; vf is worse; it usually causes cardiac arrest which is often fatal. Atrial fibrillation - from the top chamber- while not as severe, also has significant health risks. It increases the risk of stroke, which can be disabling or fatal.

I certainly agree with Dr. Rubenstein, but let's be clear: while they sound alike, the 2 rhythms are worlds apart. VF is the terminal rhythm in the majority of people who die with any form of heart disease and is fatal in about 2 minutes.. AF is treatable - one can live with it comfortably for decades and avoid strokes by taking appropriate anti-coagulant ("blood thinning") medication.
