The Full form of BPM is Beats per Minute. Heart rate is the speed of the heartbeat measured by the number of beats (contractions) of the heart per minute (BPM). The heart rate can vary according to the body’s physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is usually equal or close to the pulse measured at any peripheral point. Activities that can provoke change include sleep, anxiety, stress, physical exercise, illness, and ingestion of drugs. For adults, a normal resting heart rate ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute. You can simply check your pulse to measure your heart rate. 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. Factors that can influence your heart rate are: age, fitness and activity levels, being a smoker, having cardiovascular disease, diabetes or high cholesterol, air temperature, body position (for example, standing up or lying down), emotions, body size or medications.
