Figure 2 (A) These congestive heart failure (CHF) event-free survival curves are for patients with and without intra-left ventricular electromechanical asynchrony. There were significantly more rehospitalizations for decompensation in patients with versus without intra-left ventricular asynchrony. (B) These CHF event-free survival curves are for patients with and without interventricular electromechanical asynchrony. The presence of interventricular asynchrony did not significantly influence the number of rehospitalization over one-year follow-up.
