What is the maximum heart rate for diagnosing sinus bradycardia?

• A. 70 bpm
• B. 60 bpm
• C. 100 bpm
• D. 50 bpm

Answer: (B)

The maximum heart rate for diagnosing sinus bradycardia is defined at 60 beats per minute (bpm). Sinus bradycardia is characterized by a slower than normal heart rate originating from the sinus node, and it is typically identified when the resting heart rate falls below 60 bpm in adults. This threshold is important as it differentiates bradycardia from normal sinus rhythm, where the heart rate usually ranges from 60 to 100 bpm. Therefore, when assessing a patient for sinus bradycardia, a heart rate of 60 bpm or lower indicates the condition, making it the correct reference point for diagnosis in clinical practice.
