What is Arrhythmia in children?

An arrhythmia in children is a condition affecting their heartbeat. It can change the regular heartbeat of a child, even rhythm. If your child is diagnosed with this condition, don’t get apprehensive as it is common among children like adults. Also, it is usually harmless among children, but without early clinical intervention, it can get serious and even life-threatening. 

Arrhythmia in children indicates the heart is beating either too fast or too slow, or else skipping a beat, and may have additional beats. In most cases, the condition doesn’t need treatment, but certain cases can get serious and might need timely treatment before it’s too late. 

Decoding Normal and Abnormal Heart Rate in Children-

  • Normal heart rate- The normal heart rate of a child is 110-120/minutes 
  • Abnormal heart rate- The abnormal heart rate in children is when it increases to 200-220/ min and above.

What are the symptoms of arrhythmia in children?

Symptoms of arrhythmia in children might vary depending on what type of arrhythmia they have, however, some of the common signs that one should look for are:

  • Problems while eating, one of the noticeable signs of arrhythmia in a newborn baby
  • Weakness

  • Severe chest pain 
  • Fainting
  • Lightheadedness 
  • Dizziness 

In serious cases, the symptoms of arrhythmia in children are:

  • Syncope
  • Seizures
  • Sudden cardiac death

What are the causes of Arrhythmia in children?

Most children with supraventricular tachycardia or CVT don’t have any underlying structural heart problems. Several factors contribute to the development of arrhythmia in children. Here are these factors:

  • Genetic conditions such as long QT syndrome cause enlargement, stiffness, and thickness in the heart muscles of children.
  • Cardiomyopathy- This condition also leads to making the heart of children thick, stiff, or enlarged.
  • Medications, mainly medicines recommended to children who are seriously ill.
  • Congenital heart disease is a heart problem present at birth in newborns.
  • Electrolyte imbalances- It is linked to chemical imbalances in children’s blood.
  • Fever, sleep deprivation, inflammation, stress, and dehydration also can affect the heart rhythm of a child.
  • Bacterial or viral infections

How is Arrhythmia in children diagnosed?

Healthcare experts often diagnose arrhythmia in children during a regular checkup or diagnosing other health conditions. One can also consult about the signs and symptoms if arrhythmia in children is suspected. The pediatric cardiologist will assess the health history of a child and the family’s medical history.

  • Blood test- This test helps in determining the presence of a medication, chemical imbalance, or infection.
  • Echocardiogram- It benefits in taking pictures of a child’s heart and obtaining the details about their heart structure and functionality.
  • Electrocardiogram- This test helps to identify the electrical activity of a child’s heart. 
  • Electrophysiologic study- In this test, a tube travel is attached that travels through the child’s heart and finds the faulty electrical signal source. 
  • Holter monitor- This test benefits in determining the child’s heart electrical activity for more than 24 hours or a few days.

What are the treatment options for arrhythmia in children?

Most cases of arrhythmia in children don’t require treatment and doctors often suggest monitoring the child’s heart for some time. In some cases, the child might require treatment for an underlying cause of the condition. Here are some of the treatment options often recommended to treat arrhythmia in children:

  • Medications- Anti-arrhythmic medications such as calcium channel blockers or beta-blockers are recommended. It helps in heartbeat regulation by reducing the electrical impulses.
  • Surgical procedures- A child with a more serious case of arrhythmia might require a surgical procedure. Certain surgical procedures are there such as ablation, cardioversion, and implanted devices such as a pacemaker or implantable cardioverter defibrillator, and maze surgery.

Conclusion
