Why does a child's heart beat so fast?

When the baby is just born, parents are full of curiosity about everything about the baby. Some mothers will even use their hands to feel the baby's heartbeat and get a full sense of happiness from it. However, some careful mothers will find that the baby's heartbeat is much faster than their own. At this time, the mother may be worried. In fact, these worries are justified.

Caused by non-cardiac pathology: For example, when the baby has a fever or cries, his heart beats faster, which is called "sinus tachycardia". This is a relatively common situation and there is no need to worry too much.

Caused by heart disease: such as congenital heart disease, rheumatic heart disease, myocarditis, etc. The heart does not beat in a normal and orderly manner, but has abnormal beats or abnormal impulse conduction pathways, which causes the heart rate to accelerate. The disease is common in infants under 4 months old, often with sudden onset and symptoms such as irritability, pale complexion, cold sweats, and cold limbs.

Note: If you find that your child's pulse is too fast, you should go to the hospital for an electrocardiogram to let the doctor determine whether the arrhythmia is caused by heart disease to avoid delaying diagnosis and treatment. Causes of increased and irregular heart rate in children include: viral myocarditis, congenital heart disease, abnormal development of the cardiac conduction system, various cardiomyopathies, etc. There are also other factors, such as drug poisoning and electrolyte imbalance.

In short, when a baby is just born, all aspects of the body are still in a period of adapting to the world. If the baby does not have congenital heart problems, it is not a big problem even if the heart rate is relatively fast. Spending more time playing with the baby can help the child relax, so mothers don’t need to worry too much!
