  2. BAbnormally low blood pressure.
  3. CA fast heart rate.
  4. DA slow heart rate.
Show answer & explanation

Correct answer: C. A fast heart rate.

In medical terminology, 'tachy-' is a prefix meaning fast or rapid, and '-cardia' refers to the heart. Therefore, 'tachycardia' means a fast heart rate.

  • A. This refers to dyspnea, not heart rate.
  • B. This refers to hypotension, not heart rate.
  • D. This would be bradycardia (brady- meaning slow).

Medical Terminology: Tachycardia

A condition in which the heart beats too fast, typically defined as over 100 beats per minute.

  • Prefix 'tachy-' means fast or rapid.
  • Root '-cardia' refers to the heart.
  • Opposite of bradycardia (slow heart rate).
