[The effect of beta-receptor blockers and cardiac glycosides on the heart rate, systolic blood pressure and ST interval in submaximal ergometer exertion].
14 males at the age of 49 +/- 6.4 years with condition after myocardial infarction were loaded on the bicycle ergometer according to the criteria of the WHO. After injection of a beta-receptor blocker at the submaximal functional level the product of the pressure frequency decreased by 25% and the watt-pulse increased by 17%. The oxygen pulse and the respiratory quotient remained constant. An additional injection of glycosides did not significantly change these parameters. At the same time no falsely positive evidence concerning the behaviour of the ST-distance as criterium of withdrawal was provoked. The results of the submaximal and symptom-limited function were not falsified in the therapy with beta-receptor-blockers and glycosides, when the criteria of withdrawal recommended by the WHO are used unchangedly.
