Abstract :
The authors describe a two-channel algorithm for robust automated detection of transient ischemic ST changes. The algorithm operates as a post-processor to the ARISTOTLE arrhythmia detector. An ST segment deviation detection function is calculated as the magnitude of the ST segment vector determined from both leads. Using a variety of auxiliary functions, the algorithm distinguishes between transient ischemic ST changes and non-ischemic ST deviations caused by position-related changes in the electrical axis of the heart
