[ST segment alternams in myocardial infarct: apropos of a case].

Alternans of the ST segment is frequent in Prinzmetal's angina and is referred to a dyshomogeneity of myocardial refractoriness during ischemia. Reports of this phenomenon in myocardial infarction are, on the contrary, extremely rare. A case of alternans of the ST segment in a man with myocardial infarction is described. Based on the previous experimental reports, the hypothesis is advanced that delayed and blocked electrical activity of the ischemic area may be responsible for the event observed. This phenomenon is probably not infrequent in myocardial infarction.

Alternans of the ST segment and T wave in acute myocardial infarction.

A case of isolated alternans of the ST segment and T wave in a man with myocardial infarction is reported. Based on the previous experimental reports, the hypothesis is advanced that delayed and blocked (2:I) activity of the ischemic area may be responsible for the phenomenon observed.

Atrial repolarization: its role in ST elevation.

In four patients, ectopic supraventricular rhythm (or beats) with cephalad anomalous atrial activation and, generally, a short PR, were always associated with an ST elevation in the leads with a negative P wave. An inverted Ta wave appears to be responsible for the ST elevation.
