To determine the occurrence of inhibition of pacing by sensing of myopotentials, forty-five patients with predominant pacemaker driven heart rhythm were studied. In eleven patients with a bipolar lead system myopotential inhibition was never observed. In the remaining group (34 patients) with unipolar pacemakers myopotential inhibition was demonstrated in fifteen patients. Three of them were symptomatic, two severely. In forty new implants a silicone-rubber insulating sheath was placed against the muscular side of the pacemaker. In none of these patients myopotential inhibition could be demonstrated. The authors conclude that myopotential inhibition occurs frequently in unipolar ventricular inhibited pacemakers, and can be prevented by insulating the muscular side of the anodal surface.
为确定肌电位感知对起搏的抑制发生率，对45例以起搏器驱动心律为主的患者进行了研究。在11例使用双极导联系统的患者中，从未观察到肌电位抑制现象。在其余34例使用单极起搏器的患者中，15例出现了肌电位抑制。其中3例出现症状，2例症状严重。在40例新植入起搏器的患者中，在起搏器的肌肉侧放置了硅橡胶绝缘护套。在这些患者中均未证实存在肌电位抑制。作者得出结论，肌电位抑制在单极心室抑制型起搏器中频繁发生，通过对阳极表面的肌肉侧进行绝缘可预防这种情况。
