[ST-T isointegral map].

In this paper, clinical application of isointegral analysis on body surface potential maps during ST-T segment was reviewed. ST-T integral, which was defined as the time integral value during ST-T segment, gives an important information about the abnormalities in ventricular recovery and reflects the recovery sequence. Post-exercise recording of the ST-T isointegral maps well reflects the presence and the location of myocardial ischemia in patients with 1) angina pectoris and 2) previous myocardial infarction. The combined analysis of QRST and ST-T isointegral map in left ventricular hypertrophy can determine, whether the ST-T abnormality suggests the myocardial damages or not.
