Description
Summary:Abstract Funding Acknowledgements Type of funding sources: None. Background Cardiac Resynchronization Therapy (CRT) decreases heart failure (HF) hospitalizations and mortality and increases left ventricular Ejection Fraction (EF) in patients with dilated cardiomyopathy, left bundle branch block and QRS>130msec1. However, CRT is not beneficial in HF patients with narrow QRS3. Purpose We performed His Bundle Pacing (HBP) with high output (3.5V/1msec) in HF patients with dilated or ischemic cardiomyopathy and narrow QRS to prove hemodynamic benefit independently of the QRS duration or AV delay shortening. Methods 9 male patients with dilated cardiomyopathy (EF
