beats per minute

Explanation: 

Detailed explanation-1: -You can check your heart rate by taking your pulse and counting how many times your heart beats in 1 minute (60 seconds). Your heart rate varies depending on what you’re doing – for example, it will be slower if you’re sleeping and faster if you’re exercising.

Detailed explanation-2: -To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery-which is located on the thumb side of your wrist. When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.

Detailed explanation-3: -The rate of heartbeat is determined by a structure present in the heart known as the SA node. The SA or the Sino-atrial node is the pacemaker of the heart. It helps in the generation of electrical impulses in the heart that cause the contraction of the upper chambers present in the heart.

Detailed explanation-4: -If you count 12 beats in the span of 10 seconds, multiply 12 X 6 = 72. This means your Heart Rate or pulse, is 72 (or 72 beats per minute). Taking your pulse upon rising in the morning, or after sitting without activity for about 10 minutes, is know as your Resting Heart Rate.
