Abstract:
1. For use with a system including an implantable medical device (IMD), a method for efficiently identifying one or more cardiac resynchronization therapy (CRT) pacing parameter sets that provide improved hemodynamic response relative to an initial CRT pacing parameter set, wherein each CRT pacing parameter set includes at least two CRT pacing parameters, the method comprising: (a) obtaining information that specifies the initial CRT pacing parameter set; (b) obtaining a hemodynamic response measure corresponding to the initial CRT pacing parameter set; (c) accepting one or more user inputs that specify (d) based on the user inputs accepted at step (c), determining how many different variations of each of the at least two CRT pacing parameters, included in each CRT pacing parameter set, can be tested to identify the one or more CRT pacing parameter sets that provide improved hemodynamic response relative to the initial CRT pacing parameter set; (e) based on results of step (d), selecting and testing different CRT pacing parameter sets and obtaining a hemodynamic response measure corresponding to each of the different CRT pacing parameter sets tested; and (f) identifying, based on results of step (e), one or more of the tested CRT pacing parameter sets, if any, that provide improved hemodynamic response relative to the initial CRT pacing parameter set.
