Brazilian Guideline for Exercise Testing in Children and Adolescents - 2024.

Classes Of Recommendation: Conditions for which there is conclusive evidence and, failing that, general agreement that a given procedure is safe and useful/effective. Conditions for which there is conflicting evidence and/or a divergence of opinion about the safety and usefulness/efficacy of a procedure. Weight or evidence/opinion in favor of the procedure.

Exercise may cause myocardial ischemia at the anaerobic threshold in cardiac rehabilitation programs.

Myocardial ischemia may occur during an exercise session in cardiac rehabilitation programs. However, it has not been established whether it is elicited when exercise prescription is based on heart rate corresponding to the anaerobic threshold as measured by cardiopulmonary exercise testing. Our objective was to determine the incidence of myocardial ischemia in cardiac rehabilitation programs according to myocardial perfusion SPECT in exercise programs based on the anaerobic threshold.
