Abstract

Premature ventricular contractions (PVCs) originating from the left ventricular summit (LVS) present a diagnostic and therapeutic challenge due to their complex anatomical location. The LVS includes an epicardial area of the left ventricle bordered by major coronary arteries, which has been increasingly recognized as an arrhythmic focus. Idiopathic ventricular arrhythmias from this area may exhibit specific electrocardiographic characteristics, making accurate localization essential for effective management. Methods: This narrative review explores the primary features of this arrhythmia, emphasizing key diagnostic and therapeutic aspects, including both pharmacological and interventional approaches, considering the recent technological advances in cardiac mapping and ablations. Conclusions: PVCs originating from the left ventricular summit (LVS) exhibit characteristic electrocardiographic features. Prompt recognition of this arrhythmia may facilitate appropriate referral for targeted treatment.
