Types of arrhythmia seen in children

Although most people think of heart problems as something that happens to elderly people, children can and do experience serious cardiac conditions. Arrhythmias, also called abnormal heartbeats, are one such heart issue that can occur during childhood. There are many different types of arrhythmias that can happen during childhood, with varying degrees of seriousness. If your child has an arrhythmia, he or she will need care from a pediatric cardiologist to manage his or her condition. Here is a closer look at some of the most common forms of arrhythmias to happen during childhood.

Long QT Syndrome
Long QT syndrome (LQTS) causes longer than normal contractions in the ventricles, which are the lower chambers of the heart. Some children inherit this condition, while other may develop it as a side effect of medication.

Some of the symptoms of LQTS include fainting and a fluttering sensation in the chest. Symptoms can get worse after exercise or an intense emotional experience, such as being startled. Because this condition can lead to cardiac arrest, which in turn can lead to loss of life, it’s important work closely with your child’s pediatric to manage it.

With tachycardia, the heart beats too quickly. There are multiple forms of tachycardia. Sinus tachycardia usually occurs in response to activity or excitement, and it is not considered to be dangerous.

Supraventricular tachycardia is another form of the condition that can appear in infants, children, and teens. It can cause dizziness, chest pain, and weakness.

Ventricular tachycardia is the most rare form of the condition, but it is also the most serious. Usually, children who develop ventricular tachycardia have other heart conditions.

Complete heart block
Complete heart blocks happen when the electrical signals in the heart can’t pass normally between the chambers of the heart. Some cases of complete heart block begin in the womb.

If you child has a complete heart block, he or she may need a pacemaker.
