目的探讨病毒性心肌炎(VMC)患儿心电图改变及其与预后的关系。方法收集112例VMC患儿临床资料,患儿均行心电图、超声心动图、心脏X线检查,并进行心肌酶学检查,对各项检查的异常率进行比较分析。结果 VMC 112例患儿中,102例出现心电图改变,以各种心律失常最为常见,其次为ST-T改变和QRS低电压;心脏X线检查心影无改变者73例,出现病理性表现者39例;超声心动图出现异常改变者42例,出现酶学改变81例。心电图检查异常率显著高于心脏X线、超声心动图和酶学检查异常率,差异均有统计学意义(Pa<0.05)。经治疗后痊愈94例(83.9%),好转15例(13.4%),死亡3例(2.7%)。结论小儿VMC心电图改变以心律失常最为常见,心电图检查对VMC的诊断、治疗及判断预后具有重要意义,若患儿出现多项心电图改变则预后较差。
Objective To investigate the changes of electrocardiogram in children with viral myocarditis (VMC) and its relationship with prognosis. Methods The clinical data of 112 children with VMC were collected. The children underwent electrocardiogram, echocardiography and cardiac X-ray examination and myocardial enzymology examination. The abnormal rates of various examinations were compared and analyzed. Results Among the 112 VMC cases, 102 cases showed electrocardiographic changes, most of them were all kinds of arrhythmias, followed by ST-T changes and QRS low voltage. There were 73 cases with no changes of cardiac X-ray and no pathological changes 39 cases; 42 cases of abnormal changes in echocardiography, enzymatic changes in 81 cases. The abnormal rate of electrocardiogram was significantly higher than that of cardiac X-ray, echocardiography and enzymology, the differences were statistically significant (Pa <0.05). After treatment, 94 cases were cured (83.9%), 15 cases (13.4%) were improved and 3 patients died (2.7%). Conclusions The change of electrocardiogram in children with arrhythmia is the most common. The electrocardiogram is of great significance in the diagnosis, treatment and prognosis of VMC. If there are multiple electrocardiographic changes in children, the prognosis is poor.
