Key result
LV summit PVCs exhibit characteristic ECG features that facilitate targeted treatment.
Why the study?
Premature ventricular contractions from the left ventricular summit present diagnostic and therapeutic challenges due to complex epicardial anatomy bordered by major coronary arteries.
This review highlights the specific electrocardiographic characteristics of left ventricular summit arrhythmias to aid in accurate localization and effective management through modern mapping and ablation techniques.

May aid ECG localization for LV summit PVC ablation; leaves open prospective validation.
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.

Falco et al. (2025) conducted a review in Idiopathic ventricular arrhythmias originating from the left ventricular summit. Pharmacological and interventional approaches (cardiac mapping and ablation) was evaluated. Premature ventricular contractions originating from the left ventricular summit exhibit characteristic electrocardiographic features, and prompt recognition facilitates targeted treatment.
