Bradycardia is defined as a slow heart rate below how many beats per minute?

• A. Below 60
• B. Below 40
• C. Below 100
• D. Below 80

Answer: (A)

Bradycardia means a heart rate that is slower than normal at rest. The standard cutoff for adults is below 60 beats per minute, which is why that value is used as the definition. Below 60 bpm indicates a slower-than-normal rate, while 60–100 bpm is generally normal for resting adults. Very slow rates like 40 bpm can be considered clinically significant and may cause symptoms or require evaluation. A heart rate of 100 bpm is fast and classified as tachycardia, not bradycardia. An 80 bpm resting rate is within normal limits for many people.
