What is a satisfactory exercise tolerance test?

A satisfactory ETT requires exercising to a workload capacity of at least six METS (through Bruce Stage II or equivalent) attaining a heart rate of >85% of predicted maximum (unless on beta blockers), a rise in SBP>20mmHg without angina, and having no significant ST segment depression or elevation.
Stress radionuclide or exercise echocardiogram should be performed for symptomatic individuals, individuals with an abnormal resting electrocardiogram, or individuals who fail to meet the ETT requirements.
