Premature Ventricular Contraction Coupling Interval Variability Destabilizes Cardiac Neuronal and Electrophysiological Control

Abstract

Premature ventricular contractions (PVCs) are common in clinical practice. In structurally normal hearts, despite being referred to as benign, PVCs may lead to cardiomyopathy or even to sudden cardiac death. Recent clinical studies have identified factors that predict worse outcomes in PVC patients. Particularly, patients with PVCs showing high coupling… (More)
