Cardiac resynchronization therapy (CRT) reduces mortality and morbidity in selected heart failure patients. However, not all patients respond to CRT.We hypothesized that a novel measure of electrical dyssynchrony, sum absolute QRST integral (SAI QRST), predicts CRT response independent of QRS duration and morphology.We retrospectively analyzed baseline 12-lead electrocardiograms of SmartDelay Determined...
Recent studies demonstrate that women may respond more favorably to cardiac resynchronization therapy (CRT) than do men. The mechanisms remain unclear. To describe the effects of gender on response to CRT and to explore potential mechanisms behind these differences. Data for 846 patients from the SMART-AV trial were used to evaluate the mechanisms behind the effects of gender on CRT response...
