Energy loss by right ventricular pacing: Patients with versus without hypertrophic cardiomyopathy
Abstract
Right ventricular (RV) pacing causes left ventricular (LV) dyssynchrony sometimes resulting in pacingāinduced cardiomyopathy. However, RV pacing for hypertrophic obstructive cardiomyopathy is one of the treatment options. LV flow energy loss (EL) using vector flow mapping (VFM) is a novel hemodynamic index for assessing cardiac function. Our study aimed to elucidate the impact of RV pacing on EL in normal LV function and hypertrophic cardiomyopathy (HCM) patients.
