Abstract
The present invention is a system that utilizes different filtering techniques to provide accurate detection of changes in the ST segment of an electrogram as detected by an implanted cardiosaver system, which ST segment changes are indicative of coronary ischemia. To accurately detect changes in the ST segment of the electrogram, the cardiosaver system partitions electrograms into different partition series, preferably including the QRS and ST segments, respectively. These partition series are then passed through different analog or digital high pass filters. An alternate embodiment involves low pass filtering the electrogram and then subtracting off the filtered signal, which represents baseline wander, from the electrogram. The system also includes both implanted and external portions that provide a patient alarm if coronary ischemia is sensed.
