起搏器植入

ID: ANH00010chis
医学动画文字记录:如果你的心脏传导系统(使心脏跳动的电子系统)不能正常工作,外科医生会在你的体内植入一个起搏器。心脏是一个肌肉发达的器官,有四个心室。血液先聚集在心脏的两个上腔(或称心房),然后再流入两个下腔(或称心室)。当心室收缩时,右心室的血液被泵到肺部,左心室的血液被泵到身体的其他部位。心脏有一个天然的起搏器,叫做窦房结,或SA结。心脏起搏器通过精确确定心房和心室的肌肉何时收缩来控制心率。窦房结产生的电信号通过一条包括房室结和房室束分支的狭窄通路到达心室。这些通路合在一起被称为心脏传导系统。如果窦房结出现故障,就会导致传导系统出现问题,导致心脏跳动过快、过慢或不规则。另一种情况是,心脏束分支中可能出现阻塞,导致心脏跳动变慢或不规则。这些问题可能是由心脏病、药物或心脏手术引起的。手术前,需要检测血液和尿液。还需要拍胸部x线片,心电图(EKG)会记录心电活动。医生会在皮肤上注射局部麻醉剂,麻醉植入起搏器的部位。医生会在你锁骨下开一个小口。将起搏器导线插入锁骨下静脉,然后穿过心脏,直到到达右心房。医生将在视频屏幕上查看x线图像,以正确定位引线。一旦引线测试完毕,就会连接到脉冲发生器上。然后医生会在锁骨下的皮肤下制作一个小袋子,把脉冲发生器放在这个小袋子里,然后医生会把切口缝合起来。住院期间,医生会监测你的心率和血压,以确定心脏起搏器工作正常。在你离开之前,医生会对起搏器的设置做最后的调整。手术后,非处方止痛药,如对乙酰氨基酚或布洛芬,应该足以缓解任何疼痛。你将有大约两周不能开车。你需要定期和医生一起测试和调整心脏起搏器。
