However, as BMI increased, the ramped Bruce group had less variation in their functional capacity, METs achieved, PRP, and total time on the treadmill than the standard Bruce group (P < 0.001).The ramped Bruce produced more 152. Please enable it to take advantage of the complete set of features! No ST changes. They may also be checking to see if medications are working as expected or if you need further, more invasive testing (such as a coronary angiogram).
