Abstract
A portable apparatus and method for monitoring heart muscle electrical activity includes a plurality of electrical contacts and a monitoring unit. The contacts receive the electrical signals generated by the heart muscle of a patient and transmit the signals to the monitoring unit. A reference axis is established for each signal by the monitoring unit. Predetermined portions of each signal are then used by the monitoring unit to identify the ST segment of the signal which is then compared to the reference axis. Whenever a series of ST segments exhibit an ST deviation from the reference axis which exceeds a predetermined threshold ST deviation, the monitoring unit records data relating thereto which is used for diagnosis of myocardial ischemia.
