What is pulse rate?

Explanation:
Pulse rate is the number of times the heart beats in a minute. That’s why the option describing “how many beats” fits best—it's about the speed of the heartbeat, not its strength, breathing rate, or blood pressure. The strength of the heartbeat refers to pulse amplitude or force, not how often it occurs. The frequency of breaths describes respiratory rate, and blood pressure measures the force of blood against artery walls. In practice, you estimate pulse rate by counting heartbeats for a minute (or 30 seconds times two) to get beats per minute.
