Abstract
Objective assessment of the effect of Cardiac Resynchronization Therapy (CRT) still represents a very difficult clinical task. The ultra-high-frequency electrocardiographic (ECG) dyssynchrony (e-DYS) represents a simple ECG derived method that provides information about the ventricular electrical depolarization and thus could become helpful in CRT. The 12-lead ECG (sampling 5kHz/24bits) and echocardiography were obtained in 42 consecutive CRT patients. The e-DYS and standard QRS duration (QRSd) were automatically assessed before, just after, and 6 months after the CRT during CRT Off and CRT On. In 30 CRT responders determined by echocardiography, the e-DYS parameter was significantly lower after 6 months during CRT Off compared to state prior CRT (-9±19ms, p
