What is the normal rate for normal sinus rhythm?

• A. 60-100 bpm
• B. 40-60 bpm
• C. 80-120 bpm
• D. 100-120 bpm

Answer: (A)

Normal sinus rhythm has a resting heart rate in adults of about 60 to 100 beats per minute. This range is the standard baseline clinicians use to distinguish normal from abnormal rhythms: rates below 60 suggest bradycardia, while rates above 100 suggest tachycardia. Remember, athletes often have lower resting rates due to higher vagal tone, which can be normal for them, but for a typical telemetry assessment the 60–100 bpm range is the expected standard. When measuring, you can estimate by counting the number of R waves in 6 seconds and multiplying by 10, or count all beats in a full 60-second strip for precision.
