Which term describes a heart rate faster than normal?

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

Answer: (C)

A fast heart rate is described as tachycardia. It means the heart is beating more times per minute than normal for a resting state, typically above about 100 beats per minute in adults. This is different from hypertension and hypotension, which refer to blood pressure levels in the arteries, not how fast the heart pumps. Bradycardia is the opposite term—a slower-than-normal heart rate, usually under 60 beats per minute. Tachycardia can occur normally during exercise or stress, but if it happens at rest or is persistent, it can indicate conditions like fever, dehydration, anemia, thyroid issues, or heart rhythm problems.
