What are the units used to measure heartrate?

A person's pulse (pulse rate or heart rate) is measured in beats per minute. Here is a general standard of pulse rate (PR). Resting Pulse Rate PR < 40 BMP - Below healthy resting heart rates. PR 40-60 BPM - Resting heart rate for sleeping. PR 60-100 BPM - Healthy adult resting heartrate. PR 100 BPM - 220 BPM - Acceptable if measured during exercise. Not acceptable if resting heartrate. PR > 220 BPM -Abnormally high heart rate.
