An ischemia monitoring system has detectors for detecting the onset of an ischemic event of a tissue in subject, the end of the ischemic event and the end of a following recovery from the ischemic event, respectively. A time processor determines the duration of the ischemic event and the recovery period based on the detected onset and end times. A status processor co-processes the two determined time durations for the purpose of monitoring the ischemic status of the subject and detecting any deterioration in ischemic status for the latest ischemic event as compared to previous ischemic events that have occurred in the subjects tissue.
