目的 :探讨轮状病毒 (rota -virus)感染引起的小儿病毒性心肌炎 (Viralmyocarditis ,VMC)的临床特点。方法 :对 14 6例轮状病毒性心肌炎 (RVMC)患儿的临床资料进行回顾性分析。结果 :3个月～ 1岁的RVMC患儿 ( 64 4%)明显多于 1岁～ 6岁者 ( 3 5 6%) ,10～ 12月份发生率 ( 65 8%)明显高于其他月份 ( 3 4 2 %) ,农村患儿 ( 72 6%)明显多于城镇患儿 ( 2 7 4%) ,P均 <0 0 1;发病以轻型 ( 5 6 2 %)、中型 ( 3 9 7%)者居多 ,重型 ( 4 1%)者较少 ,P <0 0 1;肌酸激酶同工酶 (CK -MB)阳性率达 65 1%;心电图异常率达 62 3 %。结论 :RVMC主要以轻、中型患儿为主 ,发病与轮状病毒流行季节一致 ,且年龄越小发生率越高。由于早期可无明显VMC症状 ,容易忽视而延误病情 ,因此建议对轮状病毒感染患儿应常规做心肌酶谱及心电图检查 ,以便早期发现VMC ,避免漏诊或误诊 Objective: To investigate the clinical features of viral myocarditis (VMC) caused by rotavirus infection in children. Methods: The clinical data of 146 children with rotavirus myocarditis (RVMC) were retrospectively analyzed. Results: The incidence of RVMC in children aged 3 months to 1 year (64.4%) was significantly higher than that of patients aged 1 to 6 years (35.6%). The incidence of RVMC in 10-12 months (65.8%) was significantly higher than that in other months (72.4%) in rural areas were significantly higher than those in urban areas (27.4%) (P <0.01), with mild (59.2%) and moderate ) Were the majority, while those with heavy type (41%) were less (P <0.01). The positive rate of creatine kinase isoenzyme (CK-MB) was 65.1%. The abnormal rate of electrocardiogram was 62.3%. Conclusion: RVMC mainly in children with mild to moderate type, the incidence of rotavirus epidemic season, and the younger the higher the incidence. Due to the early no obvious symptoms of VMC, easy to ignore and delay the disease, it is recommended for children with rotavirus infection should be routine to do myocardial enzymes and ECG, in order to detect VMC early, to avoid misdiagnosis or misdiagnosis
