Children with myocarditis need to be regulated through medication and general measures. 1. General measures: patients need to pay more attention to rest, ensure sufficient sleep, and pay more attention to the surrounding environment quiet, appropriate to reduce or avoid activities. Patients also need to actively regulate the diet to ensure balanced nutritional intake, but avoid overfeeding, so as to reduce the heart load and myocardial oxygen consumption. 2. Drug therapy: Usually, patients can follow the doctor’s instructions to use 1,6-diphosphofructose oral solution and other drugs to improve the metabolism of cardiomyocytes. High-dose immunoglobulin can also be used to reduce myocardial cell damage through immunomodulation. In case of combined cardiogenic shock and lethal arrhythmia, corticosteroids such as adrenocorticotropic hormone are required for prompt resuscitation. It is recommended that parents pay attention to children with myocarditis and follow the doctor’s instructions to take a reasonable way of treatment.
