title: [Effect of various beta-adrenolytic drugs on heart rate and changes in left-ventricular systolic time intervals in patients with hyperthyroidism and simple goiter].
abstract: The effects of a short-term application of various beta-adrenolytic drugs on heart rate and on the changes in subperiods of left ventricle contraction have been studied in 71 patients with untreated hyperthyroidism and in 72 patients with simple goiter. The following drugs were used: propranolol, metoprolol, atenolol, pindolol, nadolol and acebutolol. It was found that those betaadrenolytic drugs which have no sympathomimetic action cause a significant decrease in heart rate both in patients with hyperthyroidism and in those with simple goiter. The effect of these drugs on heart rate was not related to the changes in blood serum concentrations of thyroxine and triiodothyronine. None of the drugs tested influenced appreciably the contraction subperiods of left heart ventricle, both in the patients with hyperthyroidism and in those with simple goiter.
