What is the recommended method for measuring resting heart rate accurately?

• A. Count the pulse for 60 seconds
• B. Count the pulse for 10 seconds
• C. Count for 5 seconds
• D. Use a blood pressure cuff only

Answer: (A)

Measuring resting heart rate accurately depends on capturing beats long enough to average out natural fluctuations from breathing and autonomic activity. Counting every heartbeat for a full 60 seconds provides the most reliable value, since short samples can miss or miscount beats and lead to errors, especially if the rhythm varies a bit or the rate is low. To do it, feel the pulse at the radial artery on the wrist (or carotid if needed) with the index and middle fingers, not the thumb, and count each beat for a full minute while the person is quietly seated with the arm supported at heart level. For consistency, ensure the person is rested and has avoided recent activity, caffeine, or nicotine. Counting for shorter periods and multiplying can introduce error, and a blood pressure cuff by itself isn’t the standard method for accurately measuring resting heart rate.
