do you know if ventricular fibrillation is the most common rhythm during cardiac arrest?

No.: The initial rhythm causing a cardiac arrest is most usually monomorphic ventricular tachycardia (62%), followed by bradycardia (17%), then polymorphic VT (13%) and finally primary vf (8%). Most of these rhythms will eventually degenerate into vf, however.

A 24-year-old member asked:

Why is ventricular fibrillation the most common rhythm of cardiac arrest?

Why not: Basically we are talking about cardiac arrest. This means the heart ceases to pump. The two options are asystole or no heart beats or ventricular fibrillation...Rapid chaotic ineffective quivering of the heart. Vf is a common consequence of heart attacks. It is also a common consequence of enlarged weakened heart (cardiomyopathy). Two common causes of death.
