Myocarditis is a limited or diffuse inflammatory disease that occurs in the myocardial cells. Whether myocarditis in children can be completely cured should be judged according to the severity of the disease, which is specifically categorized into mild myocarditis and severe myocarditis. 1. Mild myocarditis: children only show fever, cough, diarrhea and other symptoms, if timely detection, through sufficient bed rest, most children can be completely cured. 2. Severe myocarditis: children may show serious arrhythmia and even cardiogenic shock. Most of the children can be gradually restored to normal myocardial structure after early active treatment. However, there are a few children who have chronic myocarditis due to untimely early treatment or heavy inflammation of myocardial cells. When myocarditis occurs in children, it is important to seek medical attention in time to stop the progression of the disease under the guidance of a doctor, and if there are any symptoms of physical discomfort, you should go to the hospital in time to consult a physician for guidance.
