Abstract:
Objective To analyze the clinical characteristics and treatments of children with myocarditis,and to investigate the relation-ship between arrhythmia and prognosis.Methods A total of 244 patients diagnosed with myocarditis from January 2012 to December 2023 were included and retrospectively analyzed.The patients were divided into three groups:fulminant myocarditis(FMC),myocarditis(MC),and suspected myocarditis(SMC).The data included the clinical characteristics at disease onset,the treatment,and the relationship between different arrhythmias and the prognosis among the three groups.Results Among the 244 children with FMC/MC/SMC,132/244(54.1%)developed arrhythmia,ventricular arrhythmia was observed in 83/132(62.9%),and 86/105(81.9%)showed no persistent arrhythmia.The proportion of children in the FMC group who presented with palpitations,cardio-cerebral syndrome,cardiogenic shock,cardiac insufficiency,and death was significantly higher than that in the MC and SMC groups(P<0.01).Five children with third-degree(Ⅲ°)atrioventricular block(AVB)recovered after controlling their ventricular rate without a temporary pacemaker.Conclusion Most children with FMC/MC/SMC have different types of arrhythmias,of which ventricular arrhythmias are the most common,and rarely persist.FMC has severe clinical symptoms and the highest mortality rate.Ventricular tachycardia usually occurs during the administration of vaso-active drugs in patients with Ⅲ ° AVB;if the ventricular rate can be controlled promptly,these patients have a good prognosis.
