ABSTRACT:
A system including a plurality of implantable sensors, a processor, and a response circuit. Each sensor produces an electrical sensor signal related to physiologic cardiovascular events of a subject. The processor includes an event sequence detector to permit real-time detection of a time-wise sequential cascade of physiologic cardiovascular events related to myocardial ischemia of a subject and a decision module. The time-wise cascade includes at least first, second, and third physiologic cardiovascular events. The decision module declares whether an ischemic event occurred using at least one rule applied to a temporal relationship of the first, second, and third physiologic cardiovascular events. The response circuit provides a specified response if the ischemic event is declared.
