电机械分离(EMD)是指心脏存在有机的电活动而不伴有同步的心肌纤维收缩和心输出量,这实际上很少有解剖学资料证实.本文采用二维超声心动图(2—DE)研究了 EMD 病例是否存在或缺乏心肌壁和/或瓣膜运动.方法:1986年4月～1987年1月在急诊室出现或其后产生的 EMD 病例,当不能扪及颈动脉和股动脉搏动而 ECG 存在有机的电活动者纳入本研究.在心肺复苏时,暂停5秒钟,作者在剑突下部位作2—DE 检查,因这可显现心脏的四腔、二尖瓣和三尖瓣.
Electromechanical dissociation (EMD) refers to the presence of organic electrical activity in the heart without simultaneous systolic and cardiac output of myocardial fibers, which is rarely confirmed by anatomic data.In this paper, two-dimensional echocardiography (2-DE ) Studied the presence or absence of myocardial wall and / or valve motion in EMD patients.Methods: EMD cases that occurred in or immediately after the emergency room from April 1986 to January 1987 were not detectable when the carotid and femoral pulsations were pulsatile The presence of organic electrical activity in the ECG was included in the study and during cardiopulmonary resuscitation, the patient was paused for 5 seconds and the authors performed a 2-DE examination in the lower portion of the xiphoid as this revealed four-chamber, mitral, and tricuspid valves .
