ABSTRACT:
A cardiac rhythm management (CRM) system includes an implantable medical device that delivers anti-tachyarrhythmia therapies including anti-tachyarrhythmia pacing (ATP) and at least one hemodynamic sensor that senses a hemodynamic signal. When a tachyarrhythmia episode is detected, the CRM system analyzes the hemodynamic signal to determine whether and/or when to deliver an ATP. In one embodiment, a hemodynamic parameter extracted from the hemodynamic signal is used to predict the potential effectiveness of ATP in terminating the detected tachyarrhythmia episode. In another embodiment, a characteristic feature detected from the hemodynamic signal is used to determine an ATP window during which a delivery of ATP is initiated.
