Once you find your pulse, count the heartbeats over a 15 second interval. Then multiply by four. You can also count the heartbeats over a 20 second period and multiply by 3, or over a 30 second period and multiply by 2. Do not use a period shorter than 15 seconds though, as any errors are also multiplied, and it is better to multiply them by a small number than by a large one. For instance, if you count 7 pulses over 6 seconds when you should have counted 8, you will miscalculate your heart rate by 10 beats.
