[A method of diagnosis in posterior myocardial infarct].

Based on the results of examination of 58 patients with myocardial infarction, the authors propose a method for diagnosing posterior myocardial infarction by abdominal electrocardiographic mapping. The anterior abdominal wall shows the area from which one may record the direct markers of posterior myocardial infarction: abnormal Q wave, R wave regression, abnormal QS complex, as well as ST segment elevation which is typical of acute myocardial infarction. The anterior abdominal wall also defines the areas from which direct signs of inferior and lateral myocardial infarctions may be recorded.

[Adaptation to physical exertion at early stages of hypertension].

A total of 230 patients with essential hypertension without signs of circulatory insufficiency were subjected to ventilation and pulmonary gas exchange studies under dosaged physical exercises, and 140 patients were reexamined following a therapeutic course. Disturbances in the patients' adaptation to physical exercises were noted even at early stages of the disease, their therapy being found effective.
