目的研究心室晚电位(VLP)在儿童病毒性心肌炎(VM)中的临床价值。方法将2007年1月—2010年7月收治的98例病毒性心肌炎患儿分为轻、重二组,给予检测心室晚电位。结果轻症病毒性心肌炎组心室晚电位均为阴性,重症组心室晚电位阳性率为75.0%。结论心室晚电位可对病毒性心肌炎患儿的诊断及病情严重程度及预后作出判断。对重症病毒性心肌炎患儿获得早期诊断和及时的治疗,减少后遗症及病死率有一定的临床价值。
Objective To study the clinical value of ventricular late potentials (VLPs) in children with viral myocarditis (VM). Methods 98 cases of viral myocarditis admitted to our hospital from January 2007 to July 2010 were divided into two groups: light and severe, and ventricular late potentials were detected. Results The ventricular late potentials of patients with mild viral myocarditis were negative, and the positive rate of ventricular late potentials of severe patients was 75.0%. Conclusions The ventricular late potentials can make a judgment on the diagnosis of children with viral myocarditis and the severity and prognosis of the disease. Children with severe viral myocarditis early diagnosis and timely treatment, reduce sequelae and mortality have some clinical value.
