原始的埋藏式自动除颤器用一对穿透心脏的电极,既能感知心律失常,又能进行复律。它虽能感知心室颤动(室颤)和心室扑动,却不能可靠地探测全部引起低血压的室性心动过速(室速)。对原设计进行修改,增加另一对感知导线,即可用于持续性室速和室颤的复律和除颤。本文报道70例临床应用的经验、并发症和生存率。方法:1981年3月至1984年2月间连续70例病人应用埋藏式自动除颤器(AID)或双极心率感知型埋藏式自动除颤器(AID-BR)。1982年7月前植入的除颤器(AID),仅能感知室颤或正弦形室速。以后植入的属修正型(AIQ-BR),仅以平均心率检出需要中止的心律失常,既能复律又能除颤.治疗对象为由室速引起至少一次心脏停顿,或有反复发作的致命性持续性室速。大多数系经试验
The original buried automatic defibrillator with a pair of electrodes through the heart, both to sense arrhythmia, but also for cardioversion. Although it can detect ventricular fibrillation (VF) and ventricular flutter, it can not reliably detect all ventricular tachycardia (VT) that causes hypotension. The original design was modified to include another pair of sensing leads for cardioversion and defibrillation of persistent VT and VF. This article reports 70 cases of clinical experience, complications and survival. Methods: From March 1981 to February 1984, 70 consecutive patients underwent AID or BIDD (AID-BR). The defibrillator (AID) implanted prior to July 1982 only sensed ventricular fibrillation or sinusoidal VT. Subsequent implanted anastomosis (AIQ-BR), only the average heart rate to detect the need to suspend the arrhythmia, both cardioversion and defibrillation.The treatment of ventricular tachycardia caused by at least one heart arrest, or recurrent The fatal continuous ventricular tachycardia. Most are tested
