Predictors of Cardiac Resynchronization Therapy Response: The Pivotal Role of Electrocardiogram
Figure 2
Baseline ECG from CRT super responder showing several predictors of good response including sinus rhythm, long PR interval, typical LBBB with mid-QRS slurring in lateral leads, QRS duration >200 ms, and long measured by subtracting RVAT from the QRS duration. Arrow indicates the end of RVAT.
