Question

The pulse rate per minute describes the

• A. Oxygenation rate
• B. Heartbeat
• C. Pulse
• D. Both B and C

Answer 1

Answer: (B)

The correct option is B Heartbeat
This sequential event in the heart which is cyclically repeated is called the cardiac cycle. Each cardiac cycle consists of systole and diastole of both the atria and ventricles. Each cardiac cycle represents one heartbeat. The normal heart rate is about 72 beats per minute. The heart rate is same as pulse rate because the pumping action of the heart causes an increase in blood pressure in arteries that leads to noticeable pulse. Hence the pulse rate per minute describes the heartbeat.

So, the correct answer is 'Heartbeat'.
