Abstract
A portable cardiac monitor analyzes the PQ and ST portions of an electrocardiogram waveform and establishes a 'normal' or standard ST ratio deviation of the difference between the ST and PQ levels. When a subsequently measured ST ratio deviation exceeds the previously stored normal value, an alarm is indicated indicating a possible ischemic condition. The pulse rate may also be monitored to provide an alarm whenever the pulse rate rises above or falls below a predetermined value.
