[Treatment of rhythm disorders following acute heart infarction using a beta receptor blockader (Visken)].

In a group of 40 patients with acute myocardial infarction and ectopic ventricular or atrial beats or tachycardia, the effect of Visken has been tested by means of 3 i.v. injections of 0.4 mg each at intervals of 15 min. The results showed that Visken has a good effect on these rhythm disturbances and can be administered without danger, provided due regard is had to the contraindications. Beta-blockade is especially indicated when the sinus rate is raised and the conventional antiarrhythmic drugs have proved ineffective.
