In 14 patients (12 men, 2 women, mean age 51 +/- 4 years) we evaluated a new technique for intraoperative arrhythmia induction during Ventak 1550 automatic implantable cardioverter defibrillator (AICD), pulse generator placement. At the time of surgery (nine new implants, five pulse generator replacements), when the AICD pulse generator is in its final configuration with the rate sensing and patch electrodes leads inserted into the header, a #2 hex wrench was inserted into each of the rate sensing lead set screw sites. The alligator clips of a temporary pacing cable were placed on each of the hex wrenches and the remainder of the cable passed off field for attachment to a programmed stimulator or AC fibrillator. In all 14 patients, the clinical arrhythmia was induced at least twice (ventricular tachycardia in eight patients, ventricular fibrillation in six patients). No difficulties with arrhythmia induction or AICD sensing as discharge were encountered. We conclude that this technique is both a safe and effective means of intraoperative arrhythmia induction during placement or replacement in the Ventak AICD 1550 and 1600 series pulse generators.
在14例患者（12例男性，2例女性，平均年龄51±4岁）中，我们评估了一种在Ventak 1550自动植入式心脏复律除颤器（AICD）脉冲发生器植入过程中诱导术中心律失常的新技术。手术时（9例新植入，5例脉冲发生器更换），当AICD脉冲发生器处于最终配置，速率感知和贴片电极导线插入插头时，将一个2号六角扳手插入每个速率感知导线固定螺钉部位。临时起搏电缆的鳄鱼夹放置在每个六角扳手上，电缆的其余部分引出手术区域，以便连接到程控刺激器或交流纤维颤动器。在所有14例患者中，临床心律失常至少诱发了两次（8例患者诱发室性心动过速，6例患者诱发心室颤动）。未遇到心律失常诱发或AICD感知放电方面的困难。我们得出结论，该技术是在Ventak AICD 1550和1600系列脉冲发生器植入或更换过程中诱导术中心律失常的一种安全有效的方法。
