We report an unusual complication of transvenous pacing: extreme coiling of a pacemaker catheter, which formed a redundant, twisted loop protruding into the right ventricular outflow tract. This may be a result of "twiddling" (rotation) of the pacemaker generator by the patient and/or inadequate fixation of the catheter at the venous entry site. Careful fixation of the generator to the venous entry site within the subcutaneous pocket may prevent such a complication.
起搏器导管极度盘绕，形成一个多余的、扭曲的环突入右心室流出道。这可能是患者对起搏器发生器进行“摆弄”（旋转）和/或导管在静脉入口处固定不充分的结果。将发生器在皮下囊袋内仔细固定于静脉入口处可预防此类并发症。
