Overview

Brief Summary

Goal is to examine the efficy of Cardiac Resynchronization Therapy in heart failure patients with narrow QRS complex and optimized medical treatment but echocardiographic desynchronization detection as well as the positve increase of the intraoperative pressureincreasespeed in reverse remodelling and a secondary improvement of functional parameters
