What term describes a resting heart rate below 60 beats per minute?

• A. Bradycardia
• B. Tachycardia
• C. Normal sinus rhythm
• D. Heart block

Answer: (A)

A resting heart rate below 60 beats per minute is called bradycardia. Bradycardia means the heart is beating more slowly than normal when at rest. In adults, a typical resting rate is about 60–100 bpm, so under 60 is considered bradycardia. It can be normal in well-trained athletes who have a highly efficient heart, but it can also signal an issue if it’s accompanied by symptoms such as dizziness, fatigue, or fainting due to reduced blood flow. Tachycardia refers to a fast heart rate (above 100 bpm), which is the opposite condition. Normal sinus rhythm describes a normal beating pattern with a heart rate in the typical range, not specifically about being under 60. Heart block is a problem with the electrical conduction of the heart that can slow or disrupt the rhythm, but the term for a resting rate under 60 is bradycardia.
