How Calcium Channel Blockers Slow the Ventricular Response in Atrial Fibrillation
Jun 06, 2025

Atrial fibrillation (AF) is marked by chaotic atrial activity that can drive the ventricles at dangerously high rates. While the atria may be firing at 400ā€“600 impulses per minute, the AV node acts as a gatekeeperā€”filtering which signals reach the ventricles. Calcium channel blockers (CCBs), particu...
