Does mechanical dyssynchrony in addition to QRS area ensure sustained response to cardiac resynchronization therapy?

Parameters of mechanical dyssynchrony are better associated with response in the presence of a clear underlying electrical substrate. Combined presence of high SRSsept and QRSAREA, but not high QRSAREA alone, ensures a sustained response after CRT in LBBB patients.
