Ventricular premature beats

Ventricular premature beats—also referred to as premature ventricular contractions or complexes—are common cardiac arrhythmias characterized by ectopic electrical impulses originating within the ventricular myocardium or His-Purkinje conduction system prior to the anticipated sinoatrial node discharge

Affecting the cardiovascular system across both healthy individuals and patients with structural heart disease, they frequently arise from mechanisms of enhanced automaticity, triggered activity, or reentry
