The effect of increasing doses of intravenously administered propranolol on electrophysiological features of heart was studied in 17 patients with untreated hyperthyroidism by using the transesophageal stimulation method. A positive and dose-dependent effect of propranolol on the studied parameters was found with the normalization of the majority of disturbances taking place after the administration of 6 mg of propranolol. This dose was safe and well tolerated by the patients. The sensitivity of the auriculo-ventricular junction to propranolol was less pronounced during the stimulated rhythm than during the sinus rhythm.
