What are the symptoms of myocarditis in children? The following three will tell you

Myocarditis in children is a common heart disease in children. Myocarditis refers to focal or diffuse lesions of the myocardium. As it concerns the heart, myocarditis in children should not be underestimated. So, what are its symptoms?

1. Acute phase

New onset, clinical symptoms are obvious and changeable, the course of the disease usually does not exceed 6 months. Mild symptoms include fatigue, followed by sweating, paleness, palpitations, shortness of breath, chest tightness, dizziness, and lack of energy. Examination may reveal pale complexion, cyanosis around the mouth, a dull first heart sound at the apex, a soft blowing-like systolic murmur, and sometimes premature contractions. Less medium-sized. The onset is acute. In addition to the aforementioned symptoms, fatigue is prominent, and older children often complain of precordial pain. Acute onset may be accompanied by nausea and vomiting. Examination revealed a fast or slow heart rate, or an irregular heart rhythm. The child may be irritable, have cyanosis around the mouth, cold hands and feet, and cold sweats. The heart may be slightly enlarged, with dull heart sounds, a blowing-like systolic murmur at the apex, and may have a gallop rhythm and/or various arrhythmias.

2. Relocation period

After the acute phase, clinical symptoms recur, electrocardiogram and X-ray changes persist, and laboratory tests show signs of disease activity. The course of the disease is usually more than 6 months.

3. Chronic stage

Progressive heart enlargement or recurrent heart failure, with a course of more than 1 year. The chronic stage is more common in children. Some have an insidious onset and become chronic when discovered. Some are due to insufficient rest or untimely treatment during the acute stage, which leads to repeated recurrences and the chronic stage. Death often lasts for years and results in infection, arrhythmia or heart failure.
