Abstract:
Objective Explore the relationship of ventricular late potential (VLP) and the heart function of children with viral myocarditis,and provide the evidence for their diagnosis and therapy.Methods The clinical data of 152 cases of epileptic children were collected.The patient group was divided into three groups (severe arrhythmia,heart failure,and cardiogenic shock).The patient group was also divided into two groups (cardiac dilatation,and non-cardiac dilatation) according to UCG.Serum levels of cTnI and VLP in children with viral myocarditis were detected.Results The VLP was negative in the mild and control groups,but the positive rate of VLP is 75.0 ％ in the severe group.The positive rate of VLP was 60.0％ in the severe arrhythmia group,77.78％ in the heart failure group,and 100％ in the shock group.There is one kind of negative rank correlation between LAS,RMS40 and LVFS (P ＜ 0.05),and another negative rank correlation between RMS40 and LVEF (P ＜ 0.05).Conclusions The children with viral myocarditis have a favorable prognosis.The sever patient in the minority must be diagnosed in time and treated because of the critical state of viral myocarditis children.The serum level of cTnI and VLP were increased in children with viral myocarditis,and they were sensitive parameters to reflect patients’ condition.
