摘　　要：This paper reported a 25-year-old hospitalized woman complained of recurrent chest tightness and dyspnea for 3 months.The electrocardiogram showed pre-excitation and the echocardiogram showed left ventricular wall contraction reduced diffusely and moved asynchronously.In the systolic period,the regional septum basal segment moved to the right ventricle like an aneurysm.In cardiac magnetic resonance imaging examination,there was no significant myocardial fibrosis.The patient further had an endomyocardial biopsy and pathological examination showed nonspecific changes,only with mild interstitial edema.After an electrophysiological study,the patient was finally diagnosed with pre-excitation cardiomyopathy with a right anteroseptal para-hisian manifest accessory pathway.Radiofrequency catheter ablation was then performed to block the advanced pathway.6 months after ablation,the left ventricular systolic function and synchrony improved significantly,and the symptoms were alleviated.本文报道了一名25岁因反复胸闷伴呼吸困难3个月入院的女性患者。心电图显示预激波形,超声心动图检查发现左心室壁收缩力弥漫性减弱伴心室壁运动不同步,收缩期室间隔基底段局部向右心室移动,似室壁瘤表现。心脏磁共振检查显示心肌细胞无明显纤维化。心内膜心肌活检,病理结果显示为非特异性表现,仅有轻度间质水肿。电生理检查证实存在右侧前间隔显性旁路,术中行射频消融治疗,最终诊断为预激性心肌病。术后6个月复查超声心动图提示,左心室收缩功能和同步性显著提高,症状明显缓解。
