The child has fever and a rapid heart rate

Toddlers are relatively young children. If there are some problems with the body, parents are often most worried, especially heart rate problems. Because a child's heart is very fragile. After all, children are young, so various parts of their bodies are not fully developed. However, children's heart rate also has a certain normal range. If any abnormal situation occurs, it must be checked and treated in time. Why do young children have fever and rapid heart rate?

Whether it is children or adults, there are certain standards, but generally speaking, under normal circumstances, a child's heart beats faster per minute than an adult. Of course, if a child's heartbeat is too fast, it definitely means there is a problem. So what are the main causes of a child's fast heart rate? Now let's take a look at the causes of a child's fast heart rate, and I hope everyone can actively prevent and treat it.

Causes of a fast heart rate in children

(1) Physiological: Physiological tachycardia usually occurs in infancy and childhood, and some patients with ventricular tachycardia do not have organic heart disease or other systemic diseases. It usually occurs during exercise.

(2) Heart disease: Heart disease is the main cause of a rapid heart rate in children. Common causes include viral myocarditis, congenital heart disease, and heart surgery and postoperative heart disease. Cardiomyopathy and cardiac tumors are also common causes.

(3) Systemic diseases: Some systemic diseases can also cause children's heart rate to be too fast, such as severe hypoxia, asphyxia, SLE and severe infection, which may cause ventricular tachycardia after myocardial damage.

(4) Electrolyte imbalance and acid-base imbalance: Hypokalemia, hypocalcemia, and hypomagnesemia caused by various reasons are common causes of rapid heart rate.

(5) Effects of drugs and poisons: Some drugs and toxic substances can also cause children's heart rate to be too fast, such as digitalis, various antiarrhythmic drugs, etc. There are also some drug poisoning or allergies, which can cause children's heart rate to be too fast.

Experts emphasize that the causes of children's rapid heart rate are those introduced above, some of which are relatively clear, but some are unclear. No matter what causes the rapid heart rate, it must attract the attention of parents. We hope that parents can take their children to the hospital for examination and treatment to avoid more dangerous situations.
