Myocarditis in Children: Recognizing the Symptoms

Myocarditis, an inflammation of the heart muscle, can affect children of all ages. However, its symptoms are often non-specific and can be easily overlooked, especially in younger children and infants who are unable to clearly express how they feel.

Symptoms in Infants

Babies with myocarditis may not show classic signs of heart-related issues. Instead, they might become unusually fussy, irritable, or excessively tired. Feeding difficulties are common, such as poor sucking, prolonged feeding times, or a complete loss of interest in feeding. Other warning signs include pale or dusky skin color, cold hands and feet, and a generally sluggish or unresponsive demeanor.

Symptoms in Older Children

Older children who can communicate their discomfort may complain of chest pain, pressure in the chest area, or a fluttering sensation in the heart. They may also appear unusually tired, weak, or listless. These symptoms, especially when accompanied by a recent history of viral infection or flu-like illness, should not be ignored.

When to Seek Medical Help

If your child has recently had a viral infection—such as a cold or flu—and begins to show signs of fatigue, poor appetite, or changes in skin color, it's important to consider the possibility of myocarditis. In such cases, prompt medical attention is crucial.

Diagnosis and Evaluation

A healthcare provider may recommend an electrocardiogram (ECG), blood tests, or an echocardiogram to assess heart function and confirm the diagnosis. Early detection and treatment are key to preventing complications and supporting a full recovery.

Parents should be vigilant about any unusual behavior or physical changes in their child, particularly following a viral illness. Understanding the subtle signs of myocarditis can help ensure timely intervention and better health outcomes.
