In brief: 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.
