What Is The Heartbeat Rate?

Understanding the heartbeat rate:

The heartbeat rate in humans, and animals as well, is related to our body size, sex, health case, age and the demands we put on the body while doing activities.The heartbeat rate is known as the pulse, the heart rate, or the pulse rate.
They all refer to the number of contractions happening in the heart muscle per second, to pump the blood all around the body. And it can be measured at several positions.
Despite using the three terms to refer to the same number of beats per minute, there is a technical difference between both as to how they happen.



The pulse “also called pulse rate” happens when the blood is pumped from the heart through the arteries. That flow causes a bulge in the artery every time the blood is pumped. The number of bulges per minutes is called the pulse.

The heart rate is defined as the number of contractions happening in the ventricles per minute. 

The average heartbeat rate in adults can be 75 in most cases. But it varies between 60 and 100 in adults over the age of 18. It differs from one person to another according to their health case and age. For example, the average heartbeat rate of a competitive athlete may be just 40, while in newborn babies it varies between 120 and 160. It drops to 80 ~ 130 for a 2 years old baby and reaches 100 by the age of 6. After that it keeps dropping to reach only 60 in old people.

Comparing these facts about the human heart with similar researches done on animals, we can find that the heartbeat rate in small sized animals is more than that in bigger sizes. For example, the heartbeat rate may reach 1000 in small birds and only 25 for an elephant.
Hence, we realize that the heartbeat rate is higher in small sized animals and young humans and it starts to drop with aging. 

Facts about size and blood amount:

A healthy heart should pump about 5 liters of blood every minute, which is known as the average rate in normal circumstances and in rest. This rate can increase to 6 times “30 liter/minute” while being angry, stressed or when you do physical activities and sport.

Studies have shown that the human heart in males is larger than that in females, which is quite matching with the daily physical activities supposed to be done by males.

The heart is like all organs, it grows with the whole body ever since being a fetus, and its weight increases with aging. The average size of a human heart is equal to the size of a closed hand. The heart size and shape is determined by the chromosomes of the father and mother, mostly like body shape, skin tone, face features and hair color. A healthy person can suffer from certain heart problems, related to the size or any problem in the arteries, due to the chromosomes delivered from their parents. And hence we realize that some heart diseases may arise from genetic reasons.
