title: [Dependence of lactate on pulse rate, performance and cardiac volume performance quotient in rehabilitated myocardial infarct patients during bicycle ergometry].
abstract: All males of the district Cottbus who suffered from an acute myocardial infarction between 1 June 1973 and 30 June 1974 and survived the first rehabilitation phase of a definite myocardial infarction were included in the study. Their arterial lactate level, the oxygen intake, the heart rate and heart size were determined by means of standardized ergometry and radiology. Patients who had performed a rehabilitation training programme showed a higher efficiency and equal values of lactate level and heart rate compared with the patients without training programme. A close correlation also existed between lactate level and heart rate. There was no dependence on the age of the patient or the degree of heart insufficiency. These results allow to conclude that the lactate level can be used for the determination of the training intensity of patients after an acute myocardial infarction.
