Which term describes a heart rate slower than normal?

• A. Bradycardia
• B. Tachycardia
• C. Hypertension
• D. Hyperglycemia

Answer: (A)

Bradycardia is the term for a heart rate slower than normal. For most adults, a resting heart rate of about 60 to 100 beats per minute is typical, and falling below 60 bpm is considered bradycardia. In some people, especially well-trained athletes, a slower rate can be normal, but in others it may point to issues with the heart’s electrical system or be influenced by medications, thyroid problems, or electrolyte imbalances. The other terms refer to different conditions: a heart rate that’s faster than normal is tachycardia, hypertension means high blood pressure, and hyperglycemia means high blood glucose. If bradycardia causes symptoms like dizziness, fainting, or fatigue, it’s important to seek medical evaluation to determine the cause and appropriate management.
