Whereas myopotential inhibition of QRS-inhibited (VVI) pacemakers is well known, its occurrence in patients with AV sequential (DVI) pacemakers has not been reported. The present communication deals with spontaneous and induced myopotential inhibition of a multiprogrammable Intermedics unipolar AV sequential (DVI) pacemaker. The bedside maneuvers that were performed in the patient exposed the problem, therefore serving to establish the diagnosis. Although external adjustment of the sensitivity was the simple, non-invasive solution in this case, more studies are required to determine the success rate of this approach as well as the incidence and clinical significance of myopotential inhibition of unipolar DVI pacemakers.
虽然QRS抑制型（VVI）起搏器的肌电位抑制已广为人知，但在房室顺序（DVI）起搏器患者中尚未见相关报道。本文报道了一例可程控的Intermedics单极房室顺序（DVI）起搏器出现的自发和诱发性肌电位抑制情况。对该患者进行的床边操作揭示了这一问题，从而有助于明确诊断。尽管在该病例中外周调整感知灵敏度是简单、无创的解决方法，但仍需要更多研究来确定该方法的成功率以及单极DVI起搏器肌电位抑制的发生率和临床意义。
