Why Do Children with Congenital Heart Disease Experience Fatigue?

 

Children with congenital heart disease often experience lower energy levels compared to their peers.

This is commonly referred to as cardiac fatigue.

The reason lies in how the heart functions.

In CHD, the heart may need to work harder to pump blood efficiently. This increases energy use even at rest.

As a result, less energy is available for physical and mental activity.

This can lead to:

• Faster fatigue during play.
• Longer recovery after exertion.
• Reduced stamina over the course of the day.

It is important to distinguish between normal tiredness and cardiac fatigue.

Normal fatigue improves quickly with rest.

Cardiac fatigue may appear disproportionate and take longer to resolve.

External factors can also influence energy levels:

• Temperature changes.
• Illness or infection.
• Growth and development phases.

Supporting a child with CHD involves understanding these patterns.

Encouraging pacing, allowing rest, and maintaining good nutrition can help manage energy safely.

With the right approach, children can remain active while protecting their health.
