Arrhythmias coexist in patients with heart failure (HF) and left ventricular (LV) dysfunction.
Tachycardias, atrial fibrillation, and premature ventricular contractions are known to trigger a …

Electrical disturbances, such as atrial fibrillation (AF), dyssynchrony, tachycardia, and
premature ventricular contractions (PVCs), are present in most patients with heart failure …

The medical community's understanding of the consequences of premature ventricular
contractions (PVCs) and PVC-induced cardiomyopathy has been derived mostly from …

Objectives This study sought to assess the rate and outcomes of premature ventricular
contractions (PVC)–cardiomyopathy from the CHF-STAT (Survival Trial of Antiarrhythmic …

Background—Variability in premature ventricular contraction (PVC) coupling interval (CI)
increases the risk of cardiomyopathy and sudden death. The autonomic nervous system …

Background The presence and significance of neural remodeling in premature ventricular
contraction-induced cardiomyopathy (PVC-CM) remain unknown. Objectives This study …

The presence of premature ventricular contractions (PVCs) in patients with structurally
normal hearts was once considered a benign phenomenon. However, in susceptible …

Objectives This study sought to prospectively study the development and then regression of
premature ventricular contraction (PVC)-induced cardiomyopathy, with the hypothesis that …

Frequent premature ventricular complexes (PVCs) can cause an often reversible form of
cardiomyopathy. The mechanism for the development of premature ventricular complex …

Aims Radiofrequency catheter ablation (RFCA) represents an effective option for idiopathic
premature ventricular contractions (PVCs) treatment. Ablation Index (AI) is a novel ablation …
