Abstract
An example relates to a method for sensing a pulmonary artery pressure (PAP) and providing a sensed PAP signal, detecting an abnormal blood pressure (BP) condition using information from the sensed PAP signal, delivering a pacing energy to a heart, and automatically altering at least one pacing characteristic in response to the detected abnormal BP condition. 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.
