[Three cases with electrocardiographic changes suggesting myocardial infarction].

We had three cases that showed electrocardiographic changes suggesting myocardial infarction during or soon after operation. All cases were elderly for open abdominal operation complicated with carcinoma or infection. They were different from typical myocardial infarction in progress of electrocardiographic changes, increase of myocardial enzyme, autopsy and so on. Kuramoto et al. reported in some cases myocardial infarction could not be recognized at autopsy in spite of electrocardiographic changes suggesting myocardial infarction during gastric operation of the elderly, and they advocated an idea of "reversible myocardial infarction". These three cases were also thought to be consistent with this disorder.
