Mechanism of action

Antiarrhythmics act through various mechanisms including sodium channel blockade (Class I), beta-adrenergic antagonism (Class II), potassium channel blockade/repolarization prolongation (Class III), and calcium channel antagonism (Class IV). By altering the electrophysiological properties of cardiac tissue, these agents suppress abnormal electrical activity and prevent arrhythmia initiation and propagation. Medtronic's cardiac ablation solutions typically integrate antiarrhythmic therapy with catheter-based ablation procedures to treat arrhythmias.
