[Ergometric tests in cardiology (problems of standardization and automation)]. / Ergometricheskie testy v kardiologii (problemy standartizatsii i avtomatizatsii).

A method of ergometric tests furnishing a quantitative evaluation of the coronary and contractile function reserves and also ensuring safe examination has been devised. The veloergometric tests proceed under a continuous ECG and integral rheographic control with automatic throwing-off the load in case of ischemic changes of the ECG or reduction of the circulation volume. The amount of work done by the moment of throwing off the load was taken as a quantitative measure of the corresponding functional reserve. This principle served as a basis for constructing an electronic system automating the conduct and assessment of the veloergometric test. Examinations covered 890 healthy persons and patients. Future prospects for the use of biologically controlled ergometric tests are outlined.
