Electrical alternation.

ST segment alternans occurs relatively infrequently. However, it is seen in 30% of patients with Prinzmetal's angina, especially when the ST segment is markedly elevated. Ventricular arrhythmias occur frequently during ST segment alternation.

Severe coronary artery disease in the asymptomatic patient.

Asymptomatic patients more than 40 years of age who have major risk factors for coronary atherosclerosis (i.e., strong familial history for coronary atherosclerosis, hypertension, hypercholesterolemia, or diabetes mellitus or history of heavy cigarette use) should be given an exercise tolerance test. Establishing the presence or absence of coronary artery disease will help in management whether this be medical, surgical, or preventative.

Cardiac catheterization after an acute myocardial infarction.

An important question facing the profession each and every day is whether to recommend cardiac catheterization to a patient who has just had an acute myocardial infarction. Criteria have been proposed and ongoing studies are helping to establish guidelines to determine which survivors of an uncomplicated myocardial infarction can benefit from a knowledge of the coronary anatomy and ventricular function. In the case presented in this vignette the problem is related to angina recurring during the early stages of an acute myocardial infarction. Postinfarction angina often reflects subtotal obstruction of a major coronary artery that supplies either a portion of the myocardium that had infarcted or myocardium distant from the zone of the infarction. This is a high-risk group. Here the criteria are firmly established. Coronary angiography should be performed promptly to help determine whether coronary artery bypass surgery or balloon angioplasty is indicated.

[Right bundle-branch block with left hemiblock in the acute phase of myocardial infarct. Prognosis and role of cardiac pacing].

Combination of a right bundle-branch block with a left hemiblock was found in 38 of 590 patients with acuts myocardial infarction admitted to an intensive care unit (5.5%) was accompanied with a lethality of 51.5%. This severe immediate prognosis seemed related more to the degree of heart failure that to the onset of atrio-ventricular block. In 15 patients a pacing catheter was set "preventively". The late prognosis of the survivors was assessed after an observation period of 15.7 months. The efficiency of temporary pacing and its indications are discussed.
