A portable apparatus (26) and method for monitoring heart muscle electrical activity includes a plurality of electrical contacts (28a,28b,30a,30b) and a monitoring unit (36). The contacts (28a,28b,30a,30b) receive the electrical signals generated by the heart muscle of a patient (34) and transmit the signals to the monitoring unit (36). A reference axis (22) is established for each signal (10,18) by the monitoring unit (36). Predetermined portions of each signal (10,18) are then used by the monitoring unit (36) to identify the ST segment (20) of the signal which is then compared to the reference axis (22). Whenever a series of ST segments (20) exhibit an ST deviation (24) from the reference axis (22) which exceeds a predetermined threshold ST deviation (66), the monitoring unit (36) records data relating thereto which is used for diagnosis of myocardial ischemia. <IMAGE> |
