how does pulse provide a direct measure of heartbeat
Answers
Pulse is a direct measure of how frequently the heart beats – also known as the heart rate. Blood pressure is a measure of how much pressure is exerted against the walls of a blood vessel (most typically an artery). Blood pressure is typically given in two numbers, the systolic pressure over the diastolic pressure. Systolic blood pressure refers to the pressure during a heartbeat. Diastolic pressure refers to the pressure in between heartbeats. Since there is more pressure during a heartbeat, the systolic number is always higher.

Answer:
The heart rate is the number of times the heart beats in the space of a minute. ... The pulse rate is exactly equal to the heartbeat, as the contractions of the heart cause the increases in blood pressure in the arteries that lead to a noticeable pulse. Taking the pulse is, therefore, a direct measure of heart rate.
