本文对55例二尖瓣脱垂患者的心电图进行分析,其中没有一例合并冠心病或其它心脏病。二尖瓣脱垂的诊断经超声心动图,左心室造影或两者证实。结果 56例中12例有传导紊乱,但这不是由药物(如洋地黄、普鲁卡因酰胺或奎尼丁)或其它有关心脏病所引起。本组女8例,男4例。年龄17～74岁。5例患者有第一度心脏阻滞,其中一例希氏束电图显示AH间期(135毫秒)和HV间期(60毫秒)延长。3例有典型的预激综合征表现。2例有左前半阻滞,其中一例伴有不完全性右束支传导阻滞。一例患者有严重的房室传导阻滞和窦性停搏,他有反复昏厥发作的病史。一例有不完全性左束支传导阻滞。讨论二尖瓣脱垂患者传导异常的存在,进一步支持本病的病理改变并不局限于房室瓣房室传导阻滞和窦房结疾病的存在,表明心肌有弥漫的病理过程。本组3例有预激综合征,这可能是二尖瓣脱垂患者心
In this paper, 55 patients with mitral valve prolapse ECG analysis, none of them with coronary heart disease or other heart disease. Diagnosis of mitral valve prolapse was confirmed by echocardiography, left ventricular angiography, or both. Results Of the 56 cases, 12 had conduction disturbances, but this was not caused by drugs such as digitalis, procainamide or quinidine, or other related heart diseases. The group of female 8 cases, 4 males. Age 17 ~ 74 years old. Five patients had first-degree heart block and one case of His bundle showed prolongation of the AH interval (135 ms) and HV interval (60 ms). 3 cases have a typical performance of WPW syndrome. 2 cases had left anterior block, one case with incomplete right bundle branch block. One patient had severe atrioventricular block and sinus arrest, and he had a history of recurrent seizures. An example of incomplete left bundle branch block. To discuss the existence of conduction abnormalities in patients with mitral valve prolapse and to further support the pathological changes in this disease is not limited to the presence of atrioventricular valve block and sinus node disease, indicating that the heart has a diffuse pathological process. The group of 3 patients with pre-excitation syndrome, which may be mitral valve prolapse in patients with heart
