A method for early detection of a heart attack in a subject. The method includes acquiring a plurality of clinical symptoms from the subject, acquiring a gender of the subject, acquiring an age of the subject, acquiring a raw ECG signal from the subject, generating an averaged ECG signal from the raw ECG signal, acquiring a plurality of ECG features from the averaged ECG signal, designing a fuzzy inference system based on a set of rules associated with the plurality of clinical symptoms, the gender, the age, and the plurality of ECG features, and determining an occurrence of the heart attack utilizing the fuzzy inference system.

A method of processing of electrocardiogram (ECG) signals from at least one ECG lead connected to a patient includes computing an average beat from a plurality of beats occurring during a predetermined averaging interval. An onset point, isoelectric point, and a J-point of the average beat is computed to establish an S-T segment of the average beat. The isoelectric point and the J-point of the average beat are used to determine an S-T segment for each beat of the averaging interval, and the average of the S-T segments of each beat is computed and averaged with the S-T segment of the average beat.
