目的分析轮状病毒感染并发心肌炎临床特点,并判断轮病毒感染并发心肌炎与脱水程度的相关性。方法 29例轮状病毒感染并发心肌炎患儿行常规心电监测,并检测患儿心肌酶谱及肌钙蛋白的变化情况,以此判断轮状病毒感染对心肌的损害情况。结果患儿心电图异常,表现为ST-T段改变、Q-T间隙延长、期前收缩、低电压。患儿脱水程度越严重,血清肌酸激酶(CK)、乳酸脱氢酶(LDH)、肌钙蛋白T(c Tn T)及肌酸激酶同工酶(CK-MB)也越高(P<0.05)。所有患儿经对症处理后,均治愈出院,预后良好。结论轮状病毒感染会损伤患儿心肌功能,在轮状病毒感染并发心肌炎后,患儿脱水程度不断增加,心肌功能损害也随之增加。
Objective To analyze the clinical features of rotavirus infection complicated with myocarditis and to determine the correlation between rotavirus infection and myocarditis and the degree of dehydration. Methods Twenty-nine children with rotavirus infection complicated with myocarditis underwent routine ECG monitoring. The changes of myocardial enzymes and troponin in children with rotavirus infection were detected to determine the damage of rotavirus to myocardium. Results Electrocardiogram in children with abnormalities, manifested as ST-T segment changes, Q-T gap extension, premature contraction, low voltage. Serum CK, LDH, cTn T and CK-MB were also higher in children with dehydration (P < 0.05). All children were symptomatic treatment, were cured and discharged, the prognosis is good. Conclusions Rotavirus infection can damage myocardial function in children. After rotavirus infection complicated with myocarditis, the degree of dehydration in children increases continuously, and the myocardial damage also increases.
