对40例心律紊乱怀疑病毒性心肌炎(VMT)患者行心内膜心肌活检术(EMB)标本电镜进行超微结构观察,结果40例心律紊乱患者中,诊断为活动性心肌炎24例,早期扩张性心肌病8例,扩张性心肌病5例,心肌炎后遗症3例。显示电镜超微结构的检测对心肌病变的诊断率(40/40)为100％。提示了EMB对VMT诊断的可靠性和敏感性比较高。且证明EMB是一种安全、可靠、简易的方法,对VMT诊断可提供有价值的资料。
Forty patients with suspected myocarditis (VMT) with cardiac arrhythmia underwent endomyocardial biopsy (EMT) with endoscopic ultrasonography. Electrocardiography was performed in 40 patients with cardiac arrhythmia, and 24 patients with active myocarditis were diagnosed as early dilatation 8 cases of cardiomyopathy, 5 cases of dilated cardiomyopathy, 3 cases of myocarditis sequelae. The ultrastructural examination showed that the diagnostic rate of myocardial lesions (40/40) was 100%. It is suggested that the reliability and sensitivity of EMB for VMT diagnosis are high. And proved that EMB is a safe, reliable and easy way to provide valuable information for the diagnosis of VMT.
