Bradycardia is defined as a resting heart rate at or below which value?

55 BPM or Lower 65 BPM or Lower 60 BPM or Lower 75 BPM or Lower

Correct Answer:

60 BPM or Lower

Explanation:

Bradycardia means a heart rate that is slower than normal when at rest. For adults, the lower limit of normal is about 60 beats per minute. When the resting pulse is at or below that value, it’s considered bradycardic. That’s why the correct threshold is 60 BPM or lower: it includes all rates that fall at or below the normal cutoff. Values above 60 are not bradycardia, while anything at or below 60 captures slower-than-normal rates, such as 58 or 40, which can be bradycardic depending on symptoms and context. Some people with very low rates can be asymptomatic athletes or may have underlying conditions, so the exact clinical significance depends on the overall picture.
