Bradycardia is defined as?

Bradycardia is defined as?

• A. A slow, irregular heart rate below 60 bpm.
• B. A rapid, regular heart rate above 100 bpm.
• C. A slow, regular heart rate above 90 bpm.
• D. A normal heart rate but irregular rhythm.

Answer: (A)

The main idea here is identifying a heart rate that is slower than normal. Bradycardia means a resting heart rate below 60 beats per minute in adults. The best choice reflects this slow rate, and while irregularity can occur with some bradyarrhythmias, the defining feature is the rate being under 60. The other options describe fast rates (tachycardia), a slow rate that isn’t actually below 60, or a normal rate with an irregular rhythm, none of which match the core criterion of bradycardia.
