目的:分析研究致心律失常性右室心肌病患者的心电图特征以及临床表现观察。方法:选取2010年10月到2012年10月的22例致心律失常性右室心肌病患者资料进行回顾性分析,观察22例患者的临床表现、腔内电生理检查、心电图参数、超声心动图等临床资料。结果:22例患者中19例患者出现心悸和胸闷,8例患者同时伴随晕厥,1例患者有家族性猝死史。通过心电图显示8例患者显示Epsibn波,22例患者右胸导联QRS波大于等于110ms,在22例患者中出现T波倒置的患者有10例,12例患者出现S波升支时间大于等于55ms,13例患者出现室壁阻滞,15例患者显示持续性或者是非持续性心动过速。结论:致心律失常性右室心肌病一般多发于青年男性,属于造成晕厥、室壁运动异常以及室性心律失常的主要因素,Epsilon波、右胸导联QRS波大于等于110ms和T波倒置、室性心律失常作为具有特征性心电图变化,S波升支时间延长、室壁阻滞、患者右胸导联S波升支时间大于等于55ms对此病的诊断相对有所帮助,通过导管射频消融治疗实行心动过速的成功几率比较低。
OBJECTIVE: To analyze the electrocardiographic features and clinical manifestations of patients with arrhythmogenic right ventricular cardiomyopathy. Methods: The data of 22 patients with arrhythmogenic right ventricular cardiomyopathy from October 2010 to October 2012 were retrospectively analyzed. The clinical manifestations, intracavitary electrophysiological examination, electrocardiogram parameters, echocardiography Other clinical data. Results: Twenty-nine of 22 patients had palpitations and chest tightness, 8 of them had syncope at the same time, and 1 had a history of familial sudden death. Echocardiography showed 8 patients showed Epsibn wave, 22 patients with right chest lead QRS wave greater than or equal to 110ms, in 22 patients with T wave inversion in 10 patients, 12 patients with S wave rise time greater than or equal to 55ms , 13 patients had ventricular block, and 15 patients showed persistent or non-sustained tachycardia. Conclusion: The most common cause of arrhythmogenic right ventricular cardiomyopathy in young men is syncope, ventricular wall motion abnormalities and ventricular arrhythmias. Epsilon wave and QRS wave of the right chest leads are greater than or equal to 110ms and T wave inversion, Ventricular arrhythmia as a characteristic ECG changes, S wave ascending branch of prolongation, wall block, the right chest lead S wave ascending branch of the greater than or equal to 55ms on the diagnosis of this disease is relatively helpful, through the catheter radiofrequency ablation Treatment of tachycardia success rate is relatively low.
