Paced QRS Duration as a Predictor for Clinical Heart Failure Events During Right Ventricular Apical Pacing in Patients with Idiopathic Complete Atrioventricular Block: Results from an Observational Cohort Study (PREDICT-HF)

Abstract

A prolonged pQRSd has a detrimental effect on long-term cardiac function during RVAP in patients with complete atrioventricular block. pQRSd could be a useful predictor to identify patients who are at risk for heart failure events during RVAP.
