Progress in the diagnosis and treatment of pediatric myocarditis / 国际儿科学杂志

ABSTRACT

Myocarditis is an inflammatory disease of myocardium caused by a variety of factors.The most common etiology is enterovirus, followed by respiratory viruses, especially the new coronaviruses, mycoplasma, rickettsia, and toxoplasma, etc.The probability of arrhythmia is relatively high in myocarditis due to increased myocardial susceptibility, and its type may be suggestive of disease progression and prognosis.Electrophysiological changes in the cardio-myocytes are observed by electrocardiography and ambulatory electrocardiography.Echocardiography and cardiac magnetic resonance are used to detect specific changes in the internal structure of the myocardium and left ventricular systolic function and to assist in the diagnosis.For the treatment of myocarditis, in addition to general treatment, according to the needs of the condition, intravenous immunoglobulin, glucocorticoids, and receptor antagonists of some cytokines can be used.The prognosis of pediatric myocarditis is related to the type of myocarditis, the speed of progression, the degree of myocardial damage, the electrophysiological changes and the structural changes of the heart.
