In this report, we propose an objective method of deciding what is the permissible
magnitude of deviation of a patient’s electrocardiogram (ECG) from those that are
either normal or are typical of various abnormalities. In our method, we compare an
individual patient’s digital electrocardiographic data with the pooled data from the
ECGs of diagnostically uniform groups of patients. A key feature of our method is
that it considers not only the numerical differences among these sets of data, but
also the variability of the data. By doing so, our method empirically addresses the
question: How much deviation of a patient’s ECG from normal and from various abnormal
standards is diagnostically significant? To test the usefulness of the proposed method,
we studied its ability to diagnose healed inferior myocardial infarction (IMI).
