Heart Inflammation Symptoms in Children

Heart inflammation, or myocarditis, can cause various symptoms in children, often depending on the severity of the condition. One of the most common signs is a rapid or irregular heartbeat, often described as heart palpitations. These sensations may be accompanied by dizziness, chest tightness, and in more severe cases, blurred vision or even fainting spells. These symptoms typically occur when the inflammation affects the heart's electrical system, leading to arrhythmias.

Chest Pain and Discomfort

Another notable symptom is chest pain. This discomfort usually becomes more intense during deep breathing or coughing and may indicate that the inflammation has spread to the pericardium—the sac surrounding the heart. Children may complain of a sharp or persistent ache in the center or left side of the chest, which can be alarming and warrants immediate medical attention.

Difficulty Breathing and Fatigue

As the condition progresses, children may experience shortness of breath, especially during physical activity or while lying down. This symptom often signals heart failure, which can develop when a significant portion of the heart muscle becomes damaged. Along with breathing difficulties, children may feel unusually tired, dizzy, or experience persistent chest discomfort.

When to Seek Medical Help

If a child exhibits any of these symptoms—especially rapid heartbeat, chest pain, or difficulty breathing—it is crucial to seek medical care promptly. A healthcare provider will likely perform a physical exam, order blood tests, and possibly conduct imaging studies or an electrocardiogram (ECG) to confirm the diagnosis and determine the appropriate treatment plan. Early detection and treatment are essential for improving outcomes in children with myocarditis.
