Background Suppression of frequent premature ventricular contractions (PVCs) does not
systematically lead to an expected reversal of PVC-induced cardiomyopathy and …

Isolated premature ventricular contractions (PVCs) are common in clinical practice and
occur in patients with any form of structural heart and valvular disease as well as in normal …

Background Improvement of left ventricular ejection fraction (LVEF) after radiofrequency
catheter ablation (RFCA) of frequent premature ventricular contractions (PVCs) has been …

Premature ventricular contraction (PVC)-induced cardiomyopathy is increasingly being
recognized as a reversible cause of left ventricular (LV) systolic dysfunction (LVSD). The …

Premature ventricular contractions (PVCs) are a common arrhythmia that may cause
symptoms of variable severity. PVCs have recently garnered interest in their ability to induce …

Background Premature ventricular contraction (PVC) QRS duration (QRSd) and high PVCs
burden are known as a risk factor of PVC-induced cardiomyopathy (CMP). The aim of this …

Background High‐burden premature ventricular contractions (PVCs) may be an important
determinant of heart failure (HF) in patients presenting for PVC ablation. The prevalence and …

Objectives: This study hypothesizes that post-extrasystolic potentiation reflects left ventricle
contractile reserve and therefore may predict an improvement of premature ventricular …

Background: Frequent premature ventricular complexes (PVCs) can cause PVC-induced
cardiomyopathy. The value of PVC ablation in patients with preserved left ventricular …

Heart failure is common and is associated with significant morbidity and mortality. Identifying
potentially modifiable risk factors for the development of ventricular dysfunction is important …
