How do antiarrythmic drugs help in the treatment of ventricular fibrillation?

A doctor has provided 1 answer

Channel Poisons.: All antiarrhythmic medications are targeted at the channels that allow sodium, potassium, and calcium into and out of cardiac muscles, myocytes. They target certain channels at a cellular level to slow or break the abnormal rhythm. They often do nothing to fix or correct the problem.
