目的探讨小儿病毒性心肌炎的诊断与治疗方法。方法对2009年2月—2014年11月收治的100例病毒性心肌炎患儿的临床资料进行回顾性分析。结果本组100例病毒性心肌炎患儿的动态心电图中发现心律失常69例(69.00%),常规心电图发现心律失常32例(32.00%)。动态心电图与常规心电图对比检查差异有统计学意义(P<0.05)。本组患儿经治疗后显效61例(61.00%),有效33例(33.00%),无效6例(6%),总治疗有效率为94.00%。结论动态心电图检测能提高患儿心律失常的检出率和病毒性心肌炎的诊出率,对该病做到尽早发现,减少因漏诊导致病情延误的发生。抗炎、抗病毒及增强免疫力治疗能有效改善患者症状,疗效显著。 Objective To investigate the diagnosis and treatment of pediatric viral myocarditis. Methods The clinical data of 100 children with viral myocarditis admitted from February 2009 to November 2014 were retrospectively analyzed. Results In our group, 69 cases (69.00%) of arrhythmia were found in the dynamic electrocardiogram of the children with viral myocarditis and 32 cases (32.00%) of the arrhythmia were found in the conventional electrocardiogram. There was significant difference between dynamic electrocardiogram and routine electrocardiogram (P <0.05). This group of children after treatment markedly 61 cases (61.00%), effective in 33 cases (33.00%), ineffective in 6 cases (6%), the total effective rate was 94.00%. Conclusions Holter monitoring can improve the detection rate of arrhythmia and the diagnosis rate of viral myocarditis in children, make early detection of the disease and reduce the occurrence of delay due to missed diagnosis. Anti-inflammatory, anti-virus and enhance immunity can effectively improve the symptoms of patients with significant effect.
