-
aA favorable ECG pattern is indicated by the presence of a true left bundle branch block and a QRS duration > 150 ms
- Values are presented as n (%) or mean ± standard deviation. CMR = Cardiovascular Magnetic Resonance; CRT = Cardiac Resynchronization Therapy; ECG = Electrocardiogram; ICM = Ischemic Cardiomyopathy; NICM = Non-Ischemic Cardiomyopathy
