Abstract
Whereas myopo‐tential 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 myopofential inhibition of a muitiprogrammabie Intermedics unipolar AV sequential (DVI) pacemaker The bedside maneuvers that were performed in the patient exposed the problem, therefore serving to estabish 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 unipoiar DVI pacemakers
