[T-infarct in exercise electrocardiography]

In a study of 60 patients with negative T-waves in the ECG following a first myocardial infarction it was found that during milk to moderate exercise the T-wave vector turned towards normal in 36. It is assumed that during exercise the T-vector points towards the region of maximum ischemia, i.e. the border of the recent infarction. The conclusion is drawn that unexpected transitory normalization of the T-wave after myocardial infarction means "worse" not "better". It is recommended that follow-up ECGs after myocardial infarction should always be taken at complete rest.
