title: Supplementary static effort during dynamic exercise. Its influence on electrocardiogram, haemodynamic and metabolic adaptation of circulation in coronary patients.
abstract: Twenty men with coronary heart disease underwent the following exercise tests: a) bicycle ergometry, b) 5 kilometre walk and c) short march with a 5 kilogram weight carried in one hand. In each performed test during maximal work the following parameters were determined: oxygen uptake (VO2), plasma noradrenaline (NA) and lactate (LA) concentrations. ECG was monitored continuously and blood pressure was measured. It was found that a supplementary static load added to the dynamic work during short march with a weight resulted in the highest NA concentration. In that test, the rate-pressure product (HR X BPs) also increased and a greater ST segment depression and aggravation of arrhythmia were noted as compared to the findings obtained during the 5 kilometer march and also in the classic ergometric test.
