What causes a child's heart rate to be too fast?

The heart is the most important organ in the human body. If the heart stops beating, a person's life will come to an end. However, if the heart beats too fast, it can cause great harm to the body. Especially during childhood, many children experience a rapid heart rate. In this regard, only by finding the cause can we effectively solve the problem of children's fast heart rate. So what causes a child's rapid heart rate?

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 to 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 need a lot of oxygen and nutrients. The more you need, the more waste you excrete. In this case, the heart needs 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 quickly. A child's heartbeat is naturally faster than an adult's, and sometimes it depends on the child's situation.

Children are more active than adults. If the child is active and looks healthy, then there should not be any major problems. You can let your child stabilize for a few minutes, such as before going to bed, and measure your child's heartbeat. If the heart rhythm is unstable when the child is stable, it is recommended to take the child to the hospital. In addition, fever and viral infection can cause a rapid heartbeat, but this is fine as long as you recover quickly.
