Should the attainment of predicted heart rate maximum be used as an exercise test end point?
نویسنده
چکیده
Age predicted maximum heart rates based on the formula 220-age have long been used in fitness and clinical settings to gauge exercise intensity and predict exercise test end points. Exercise stress tests have in some cases been routinely terminated based on the attainment of this equation, despite recommendations that age predicted maximum heart rates should not be used as an exercise test endpoint when screening for myocardial ischemia. Here we describe two cases that challenge the practice of terminating exercise stress tests based on predicted maximum heart rates during screening for myocardial ischemia.

BACKGROUND One way of defining an individual's heart effort is to calculate the maximum heart rate to be expected given their age, but the reinnervation seen in patients who have received heart transplants makes for different calculations from patients who have suffered heart failure. The purpose of this study is to evaluate heart rate dynamics (rest, peak and percentage of predicted heart rate...
