Abstract:
A method of monitoring the coronary status of a patient permitted to undertake normal activities after a cardiac episode comprising the steps of:(a) attaching a set of electrodes to a patient after the cardiac episode to enable to undertake normal activities of life after the episode;(b) forming a set of time dependent signals from the set of electrodes;(c) correcting the signals for systematic errors;(d) time multiplexing the signals;(e) converting the multiplexed signals into digital values having a data rate;(f) reducing the data rate while preserving patient cardiac condition in the reduced data rate;(g) transmitting the reduced data rate patient cardiar condition;(h) receiving at a central location the transmitted reduced data rate patient cardiac condition;(i) wherein the steps of transmitting and receiving are limited by the pass band of a connective link between the patient and the central location;(j) storing cardiac heart beat signal shape and condition data for the patient at the central location;(k) electronically comparing the received reduced data rate patient cardiac condition with the stored coronary condition data to make a determination of patient cardiac condition departing from patient related cardiac heart beat signal shape; and(l) electronically responding to the step of comparing to send to the patient a signal indicative of patient cardiac conditions or indicative that medical intervention has been sent.
