本文用心内膜额外刺激起搏技术测定心房有病变者心房的传导性和兴奋性,发现P波时间延长者其心房过早反应的传导时间与P波时间正常者不同,并以此解释早期发生的房性过早搏动对反复性房性搏动和心房颤动所起的触发作用.方法:20例窦性节律的病人,男性11例,女性9例;年龄28～84岁.其中7例患动脉硬化性心脏病,5例患高血压性心血管病,1例原发性心肌病,另7例无明显器质性心脏病.按P波间期将病人分成二组,7例病人P波间期<115毫秒,构成第一组;
In this paper, cardiac endocardial stimulation of pacing techniques were measured atrial lesions with atrial conduction and excitability and found that P-wave prolongation of the atrial premature reaction conduction time and P-wave time is normal, and to explain the early occurrence Of premature ventricular pulsatile pulsation on recurrent atrial beats and atrial fibrillation.Methods: Twenty patients with sinus rhythm were enrolled in this study, including 11 males and 9 females, aged from 28 to 84. Among them, 7 had arterial Sclerosing heart disease, 5 cases of hypertensive cardiovascular disease, 1 case of primary cardiomyopathy, the other 7 cases without obvious organic heart disease.The patients were divided into two groups by P wave interval, 7 patients with P wave Interval <115 ms, forming the first group;
