Why is the baby's heart beating fast?

In fact, there is no need to worry too much, as a baby's heartbeat is faster than that of an adult. Read this article to find out.

In fact, these are just unnecessary worries of parents. Experts say that it is normal for a baby to have a fast heartbeat and parents do not need to make a fuss about it.

In the process of taking care of children, careful parents will find that children's heartbeats are faster than adults'. Abnormal heartbeats often indicate health problems. Therefore, figuring out why children have fast heartbeats will obviously help parents understand their children's health. So, why do children have fast heartbeats?

Experts say that children's heartbeats are definitely faster than adults', so children's body temperature will be slightly higher than adults'. This is also one of the reasons for the fast heartbeat, but there is no need to be nervous! Children's fast heartbeat is related to their vigorous metabolism and the dominance of the sympathetic cardiac nerves.

Every time the heart beats, the left ventricle ejects blood into the aorta. Blood is transported to all parts of the body through the aorta for blood circulation, eliminating carbon dioxide and waste from the body and inputting oxygen and nutrients to ensure the body's metabolism. Because children's hearts are more excitable, the younger they are, the faster their heartbeats. Moreover, the heart rate will also increase when the baby's activity level increases, when crying, when he is nervous or has a fever. It is normal for children to have a fast heartbeat, and it is common for children to have a heartbeat over 100.

Generally speaking, the normal heart rate range for children is: 80-140 beats/minute for children under 1 year old; 80-120 beats/minute for children aged 1-6 years old; 60-100 beats/minute for children over 6 years old. However, the above frequencies should be in a quiet state. If the child is active or participates in physical exercise, the heartbeat can be significantly faster. Children are in the period of growth and development, and they need a lot of oxygen and nutrients. The more they need, the more waste they excrete. This requires the heart to beat faster so that the blood can flow faster, bringing more oxygen and nutrients into the body and transporting useless waste out of the body more quickly. A child's heart beats faster than an adult's, and sometimes it depends on the situation she is in. Children move more frequently than adults. If she is an active child and looks healthy, then there should not be any big problem. You can let her stay stable for a few minutes, such as before going to bed, and measure her heartbeat. If her heart rate is unstable when she is stable, it is recommended that you take her to the hospital. In addition, fever and viral infection can cause rapid heartbeat. As long as it recovers quickly it's fine.

Generally speaking, when a child has a fast heartbeat, the reasons for this are generally what are described in the article. After understanding the causes of a child's fast heartbeat, parents should also pay attention to whether the child's heartbeat is within the normal range. Once any abnormality is found, medical treatment should be sought as soon as possible.
