心臟除顫[1](cardiac defibrillation[2][3])简称除颤(defibrillation)、去颤,是利用医疗器械、特定药品、手术方式终止心脏颤动的治疗方法。最常见的除颤是用电击终止心房或心室纤颤,称为电除颤(electric defibrillation)。
去颤对于危及生命的心律不整,如心室颤动、无脉性心室频脉是一种常见的治疗手段,常见的具体方法为使用去颤器(也称除颤器)给予心脏治疗剂量的电能。雖然原理目前尚未明瞭,但普遍認為这么做能使极大部分的心肌去极化,终止心律不整,并使窦房结中的节律点能重建窦性心律。
電擊
[编辑]电除颤是使用一定强度的电流作用于心脏,电击(shock)使全部或部分心肌除极后,心脏在自律性最高的起搏点重新主导心脏节律(通常是窦性心律)的方法。
心脏除颤器(cardiac defibrillator)又称去颤电击器、除颤器、去颤器,分为体外型、静脉置入型、植入型,依不同需要使用[4]。
去颤实际上是将心脏电击停跳,制造心脏停搏。心室顫動中心脏电信号活动紊乱,窦房结无法发出信号控制心脏有效进行血液循环,因此使用外部电流直接使得心脏停跳。停跳后,立刻进行CPR,以求窦房结自行恢复心跳。因此,对于已经心脏停搏的病人,是不进行电击的,电击了也是心脏停搏。仅对心律失常的病人电击。
电复律与电除颤
[编辑]按原术语 electric cardioversion[5][6](电复律)与 electric defibrillation[7][8](电除颤)意思,前者是使心律失常恢复至正常节律,后者是终止心脏颤动(心房颤动、心室颤动);因此电除颤属于一种电复律。但在临床上,英语与汉语都有混用的情形,合称复律除颤(cardioversion-defibrillation[9]);或是更常将“电复律”等义于同步电复律,尽管所谓“电复律”也用于治疗心房颤动;而“电除颤”等义于非同步电复律,尽管所谓“电除颤”治疗的疾病不一定是心脏颤动的情况,而可能是无脉性室速[10][11][12]。
- 同步电除颤(synchronized defibrillation[13])或同步电复律(synchronized electroversion[14]/cardioversion[15]),是心电图上能检测到心室波(R波)进行的电除颤,适用于心房颤动、心房扑动、室上性心动过速、室性心动过速等快速心律失常[16]。
- 非同步电除颤(unsynchronized defibrillation[17])或非同步电复律(unsynchronized electroversion/cardioversion[18]),是心电图上不能检测到心室波(R波),在任意时刻用强脉冲放电使所有心肌纤维同时除极的过程,适用于心室颤动、心室扑动时[19]。
心脏复律除颤器(cardioverter-defibrillator)又称复律除颤器,是具有支持性起搏和抗心动过速起搏,且能自动感知与识别室性心动过速或心室颤动发作,并立即放电进行低能量复律或高能量除颤等作用的装置[20][21]。
