Abstract:
1. A system for detecting ischemia comprising: at least one lead configured for placement within a patient, the at least one lead comprising a sensor operative to sense ventricular activity and to generate a corresponding signal; and an implantable medical device configured for connection to the at least one lead, the implantable medical device comprising circuitry operative to receive signals from the sensor corresponding to ventricular activity, to open a window a predetermined time after sensing the ventricular activity, wherein the window is shorter than a ST segment, the circuitry being further operative to determine an amplitude value within the window, and to process the amplitude value to detect ischemia; wherein the circuitry is operative to open a window by opening the window at a first time if the ventricular activity is intrinsic, and at a second time if the ventricular activity is paced.
