[Diagnostic importance of visken -- an adrenergic beta receptor blocking agent].

Among the newest beta-blocking agents visken is the one that either produces no or very little adverse inotropic effect. In some groups of patients with organic and neurotic cardiac disorders, screened as a result of a careful clinical examination, changes that occurred on the ECG with 12 leads following an intake of a single visken tablet (5 mg) were studied. Ingestion of visken was not seen to bring any improvement in the ECG findings in 88 per cent of 50 patients with organic disorders, most of whom had sclerosis of the coronary arteries and hypertensive disease attended by a high diastolic pressure.
