[Respiratory metabolism in patients during exercise therapy in the early period of acute myocardial infarction].
Respiratory and cardiocirculatory response to rehabilitation calisthenics in 30 patients, aged 39-66 years, with recent myocardial infarction was studied. Respiratory exchange (Douglas-Haldane method), heart rate, blood pressure, oxygen pulse and electrocardiogram during exercise were investigated. Rehabilitation was performed between the 4th and 21st day of myocardial infarction, in 4 periods with gradually increasing effort, according to the model A designed at the Cardiology Institute in Warsaw. The time of exercises was 10-18 min, depending on the period of rehabilitation. It was found that lung ventilation, tidal volume, oxygen uptake and carbon dioxide output were increased by 20-40% during exercise of the I and II periods of rehabilitation and by 60-100% in the III and IV periods of mobilization. Energy cost of calisthenics rehabilitation was in the lightest case 13 kJ/min. The most increase in respiratory exchange caused exercises performed in sitting position, walking and stair climbing. The last type produced also the highest rise in heart rate (mean 20%) and systolic blood pressure (mean 17% of resting values).
