The FAA expects testing to achieve 100% of Maximum Predicted My husband recently had a nuclear stress test done and the results are confusing. The Bruce protocol METs calculator allows you to interpret the results of the Bruce protocol stress test. Also known as the exercise tolerance test, it is used to estimate endurance athletes' overall fitness or to detect weak heart conditions. By gradually increasing the intensity of the physical activity, a person's maximum METs is measured. This involves starting on a treadmill at a speed of 1.7 miles per hour and a 10% incline. The Bruce protocol is a standard test in cardiology and is comprised of multiple exercise stages of three minutes each.

Complete heart block occurs when electrical impulses in the hearts upper chambers (atria) don't travel down to the lower chambers (ventricles). The 12-lead ECG should be recorded at rest, supine and standing; one or more times during each stage of exercise; at the end of each stage; at peak exercise; and every minute during recovery for at least five minutes, or until the tracing returns to baseline. Master's Two-Step test was sometimes used, but it was too strenuous for many patients, and inadequate for the assessment of respiratory and circulatory function during varying amounts of exercise. There are 7 such stages and only very fit athletes can complete all 7 stages. EMCCG. (2021).
