Abstract
A system for detecting acute ischemia includes at least two sensors configured for obtaining electrical signals from a patient's heart, analog-to-digital converter circuitry for digitizing the signal to produce data segments, and a processor configured to analyze data segments to determine if they represent an abnormal heart rhythm. Certain types of abnormal rhythm segments are also checked for acute ischemia. If enough of the abnormal heart rhythm segments manifest acute ischemia, a first type of alarm event is generated. If persistent abnormal heart rhythm segments do not manifest acute ischemia, a second type of alarm event is generated.
