Comments about the electrocardiographic signs of right ventricular infarction.

This manuscript was written in an effort to emphasize the points made by Porter et al. (Clin Cardiol 1997; 20:971-973). Right ventricular infarction may be erroneously interpreted as an anteroseptal infarction because of elevation of the S-T segments in leads V1-V4. The two can be separated when, using the Grant method of analysis, the S-T segments are represented as vectors: the mean S-T vector is directed inferiorly, to the right, and anteriorly when there is an inferior-right ventricular infarct, and superiorly, to the left, and anteriorly when there is an anteroseptal infarction. Other aspects of right ventricular infarction are also discussed.

Abnormalities of the S-T segment--Part I.

The usual normal S-T segment of the surface electrocardiogram (ECG) contributes little to the diagnostic procedure. When the S-T segment is too long or too short, or when it is displaced upward or downward, it is commonly abnormal. Under such circumstances, an S-T segment abnormality usually contributes considerable diagnostic information. When the Grant method of ECG interpretation is used, it is possible to perceive abnormalities of the S-T segment that may otherwise be ignored or misinterpreted. This paper describes the method of identification and the significance of primary and secondary S-T segment abnormalities. When a mean vector constructed for the S-T segment displacement seen in 12 ECG leads is relatively parallel with a mean vector representing the T wave, it is, with a few exceptions, part of the repolarization process and is therefore part of the T wave. This may be called a secondary S-T segment abnormality. When a mean vector constructed for the S-T segment displacement seen in 12 ECG leads is not relatively parallel with a mean vector representing the T wave, it is, with a few exceptions, not part of the repolarization process and is therefore not part of the T wave. This may be called a primary S-T segment abnormality.

Computer errors in electrocardiography.

Computer interpretation of electrocardiograms is far from adequate. This paper highlights a particular type of computer error that is merely symbolic of the large number of errors the computer can make. In addition to computer errors in electrocardiography, it is likely that computer interpretation has diminished the ability of physicians to interpret electrocardiograms.
