Why is an ECG Important in Pediatrics?
In pediatrics, ECGs are crucial for diagnosing congenital heart defects, monitoring
heart health, and evaluating symptoms such as chest pain, palpitations, and syncope. Early detection of heart abnormalities in children can lead to timely interventions and better outcomes.

Symptoms like dizziness, fainting, or palpitations
Before participating in competitive sports
Follow-up for known heart conditions
How is an ECG Performed on a Child?
Performing an ECG on a child is similar to an adult, but special consideration is given to the child’s age and size. The child will lie down, and electrodes are placed on their chest, arms, and legs. The procedure is painless and non-invasive. It is essential to keep the child calm and still during the test for accurate results.

Evidence of
myocardial ischemia or injury
Electrolyte imbalances
Effects of certain medications
Common Pediatric ECG Abnormalities
Some common abnormalities that may be seen in pediatric ECGs include: Wolff-Parkinson-White (WPW) syndrome
Long QT syndrome
Hypertrophic cardiomyopathy
Complete or incomplete heart block
Each of these conditions requires specific management and follow-up.
How Often Should an ECG be Done?
The frequency of ECGs depends on the child’s health status and specific conditions. Children with known heart conditions or those with symptoms may need regular monitoring, while others might only need an ECG as a one-time test for a particular concern.
What Should Parents Know?
Parents should understand the importance of an ECG in diagnosing and monitoring heart conditions. They should ensure the child follows the cardiologist's recommendations and attends all follow-up appointments. If any symptoms such as chest pain, fainting, or unusual fatigue occur, they should seek medical advice promptly.
