This case report describes myopotential interference with an automatic AV sequential pacemaker (DDD) producing repetitive firing of the ventricular channel up to a rate of 160 and occasional suppression of the ventricular output. A silastic boot which covered the pacemaker did not prevent sensing of electromyopotentials. The problem was partially corrected by decreasing the sensitivity of the ventricular channel. The ventricular response to myopotentials sensed by the atrial channel was limited by decreasing the maximum programmed rate to 120/minute.
本病例报告描述了肌电位干扰自动房室顺序起搏器(DDD),导致心室通道重复放电,频率高达160次/分钟,并偶尔抑制心室输出。覆盖起搏器的硅橡胶护套未能防止肌电信号被感知。通过降低心室通道的灵敏度,问题得到了部分纠正。通过将最大程控心率降至120次/分钟,限制了心房通道感知的肌电位对心室的反应。
