It is with this very data- Since, I have exercise-phobia A follow-on nuclear perfusion stress test was done - S-T depression of 1. maximum heart rate. The FAA expects testing to achieve 100% of Maximum Predicted Heart Rate (220 minus your age) and nine minutes duration unless medically contraindicated or prevented by symptoms such as fatigue, leg cramps, shortness of So, if youre 40 years old, the maximum predicted heart rate is 220 40 = 180. The Standard Bruce exercise test protocol requires a change in speed and grade every 3 minutes. However, one study of men and women set to undergo stress testing didnt find anxiety was predictive of a positive result. Calibrations for grade and belt speed were checked at frequent intervals. The 10 minute period does not have to be exact; it is not actually what the test is determined by, but instead it is recommended simply as a way to prepare an individuals muscles for the rest of the test. The .gov means its official. The Bruce protocol is a diagnostic test used in the evaluation of cardiac function, developed by Robert A. Bruce.
