Background:Ventricular arrhythmias (VAs) remain a leading cause of sudden cardiac death (SCD) in patients with ischemic and nonischemic cardiomyopathy, driven substantially by sympathetic nervous system overactivity and elevated catecholamine tone. Beta-adrenergic receptor blockers have been a cornerstone of pharmacotherapy for decades, yet their antiarrhythmic efficacy extends well beyond simple heart rate reduction. Objective:This narrative review synthesizes current evidence on the antiadrenergic mechanisms by which beta-blockers suppress ventricular arrhythmogenesis, evaluates their clinical impact in ischemic and nonischemic cardiomyopathy populations, delineates differential effects among specific beta-blocker agents, and details their safety profiles and clinical limitations.
