This is true if you cant achieve 85% of your maximum heart rate but dont experience any electrocardiogram (EKG) changes that suggest youre experiencing ischemia. The Bruce protocol was used to carry out the exercise tests. Given the protocol, I think this is about 5 METS (?) There were 5103 deaths The testing protocol could be adjusted to a patients tolerance, aiming for 6 to 12 minutes of exercise duration. Maximum heart rate (MHR) is often calculated with the formula 220-age, which is quite inaccurate. If beta-blockers, calcium channel blockers, or digitalis-type medications are being taken to inhibit heart rate response, it may be necessary to discontinue the drugs for 48 hours before testing in order to attain adequate heart rate. Customizable. Every 3 minutes the speed and grade increase to a maximum of 6.0 miles per hour and 22% grade. Bookshelf Of those ages 35 to 60, 5.1% had an abnormal stress test.
