A new approach to the qualitative assessment of the reaction to physical loading during bicycle ergometry of patients following aortic prosthesis

: The paper is concerned with the objectivization of qualitative assessment of a response to exercise testing during rehabilitation of patients after aortic valve replacement. The authors propose methods for a study of hemodynamic provision of submaximum and threshold exercises confirming significantly a higher myocardial reserve in patients after submaximum exercises. Hemodynamic characterization of different types of threshold reactions has shown that a common feature in the majority of patients is a decrease in cardiac ejection during exercise testing, mainly as a result of ino- or chronotropic depletion. A significant increase in the number of submaximum bicycle ergometric exercises is an important criterion of the efficacy of a rehabilitation program.
