[Ergometric studies in the practice of medical aviation expertise].
In order to assess standard and relative indices of ergometry, exercise tolerance and physical work capacity, 64 members of flight crews with compensated atherosclerotic coronary cardiosclerosis (aged 28 to 56) were examined. The studies were carried out using the Siemens cardiopulmonary complex at rest, at work load of 100 Wt/min for 5 min and during recovery for 10 min. At the initiation of the experiment and during recovery ECG in 12 standard leads was recorded every other minute. With respect to the age and clinical data, the test subjects were subdivided into two groups. Electrocardiographic study revealed insufficiency of coronary circulation in 63.7% of the first group and in 80,6% of the second group test subjects. Ergometric measurements showed a distinct decrease of the chronotropic, inotropic and aerobic cardiac reserves, especially of the second group test subjects. Ergometric parameters correlated well with the clinical and electrocardiographic data. The results can be used in the diagnostics, evaluation of cardiopulmonary functional and reserve capabilities, and support of expertise recommendations.
