摘要:
According to a system or method, information indicative of a cardiac depolarization signal can be obtained. Information indicative of an acoustic signal from an implantable acoustic sensor included as a portion of an implantable therapy device can be obtained. A feature indicative of an R wave can be identified from the information indicative of the cardiac depolarization signal, and a feature indicative of an S2 heart sound can be identified from the information indicative of the acoustic signal. A time interval between an instant corresponding to the feature indicative of the R wave and an instant corresponding to the feature indicative of the S2 heart sound can be determined. Using information about the determined time interval, an adjusted pacing therapy parameter can be provided for use in a pacing therapy to be provided by the implantable therapy device.
