Objective To investigate clinical characteristics of children with fulminant myocarditis.Methods The 50 cases of fulminant myocarditis who were treated in our hospital from January 2007 to May 2013 were retrospectively analyzed, the children's gender, age, clinical manifestations and treatment, prognosis were summarized.Results Among fifty cases of fulminant myocarditis in children, 16 cases(32.0%) had digestive tract symptoms, 14 cases (28.0%) had cardiovascular system symptom, 8 cases (16.0%) had the nervous system symptoms, asperger syndrome was as the starting performance in 26.0% of children, 46 cases (92.0%) had abnormal electrocardiogram, positive rate of myocardial enzyme index and heart color doppler flow imaging was 48.0% (24 cases) and 50.0% (25 cases); 32 cases were given immunoglobulin infusion, 44 cases applied prednisolone, 28 cases with Ⅲ degree atrioventricular block were installed temporary pacemaker based on the comprehensive treatment, 4 cases were given final installation permanent pacemaker; For children occurred ventricular tachycardia, 6 cases applied lidocaine, 7 cases applied amiodarone, 8 cases were given synchronous cardioerter, 17 cases'tachycardia were terminated, one case installed temporary pacemaker after converting sinus rhythm, 2 cases with ventricular fibrillation died.Conclusion Children with fulminant myocarditis diverse symptoms, most are not typical, misdiagnosis rate is high; Comprehensive analysis of the results of electrocardiogram, echocardiography and myocardial enzymology markers may improve the diagnosis of fulminant myocarditis, may indicate the severity and prognosis.□
