First, determine your age. For this example, the person is 50 years old.

Next and last, just use the formula above to estimate your heart rate during a stress test.

STHR = 220 – A

STHR = 220 – 50

STHR = 170 BPM

This heart rate is only an estimate, the true heart rate someone reaches during a stress test can only be measured directly.
