    摘要: A system senses a cardiac signal for diagnostic and/or therapy control purposes using a first set of electrodes and switches to a different second set of electrodes for recognizing cardiac events in the cardiac signal. In various embodiments, the cardiac signal sensed using the second set of electrodes is compared to the cardiac signal sensed using the first set of electrodes, and the cardiac events in the cardiac signal are each recognized using an outcome of the comparison.

    摘要: A system and method for automatically analyzing a cardiac signal, including the step of providing an episode database on a computer storage medium including a plurality of episode data records of one or more patients. Each episode data record includes a cardiac signal from at least one data-generating device. The method also includes the step of selecting one or more of the N beats to be one or more beat templates, for at least a first cardiac signal having N beats. Another step is determining a value K for the cardiac signal using a computer system where K beat templates can represent all the N beats in the cardiac signal.

    摘要: An implantable medical device delivers anti-tachyarrhythmia therapies including anti-tachyarrhythmia pacing (ATP). When a tachyarrhythmia episode is detected, the implantable medical device analyzes cardiac cycle length stability to determine whether and/or when to deliver an ATP. In one embodiment, the cardiac cycle length stability is measured by existence of stable ventricular tachyarrhythmia clusters (SVTCs) during the tachyarrhythmia episode. Each SVTC includes at least a specified minimum number of heart beats over which the cardiac cycle lengths meet a stability criterion.

    摘要: 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.
