摘要： A cardiac rhythm management (CRM) system includes an implantable medical device that delivers anti-tachyarrhythmia therapies including anti-tachyarrhythmia pacing (ATP) and a hemodynamic sensor that senses a hemodynamic signal. The implantable medical device includes a hemodynamic sensor-controlled closed-loop ATP system that uses the hemodynamic signal for ATP capture verification. When ATP pulses are delivered according to a selected ATP protocol to terminate a tachyarrhythmia episode, the implantable medical device performs the ATP capture verification by detecting an effective cardiac contraction from the hemodynamic signal. The ATP protocol is adjusted using an outcome of the ATP capture verification.

The detecting an abnormal BP condition can include detecting various forms of hypertension or hypotension. The automatically altering the at least one pacing characteristic can include automatically altering at least one of a pacing rate, a pacing waveform, an atriventricular (AV) delay, an interventricular (VV) delay, a pacing mode, or a pacing site. The method can also include delivering vagal nerve stimulation and automatically altering the vagal nerve stimulation in response to the detected abnormal BP condition. The detecting the abnormal BP condition can also include using a sensed auxiliary physiological parameter.
