Echocardiographic AV-interval optimization in patients with reduced left ventricular function

Abstract

BACKGROUND Ritter's method is a tool used to optimize AV delay in DDD pacemaker patients with normal left ventricular function only. The goal of our study was to evaluate Ritter's method in AV delay-interval optimization in patients with reduced left ventricular function. METHODS Patients with implanted DDD pacemakers and AVB III degrees were assigned to… (More)
