저자들은 3도 방실전도 차단으로 인공심박동기를 삽입후 조율 유도의 절연손상으로 인해 조율 유도의 저항변화 없이 조율 역치와 감지도가 변하면서 자세 변화에 따라 간헐적인 조율 장애와 감지 장애를 보이는 환자에서 새로운 조율 유도 삽입 후 성공적으로 치료하였기에 이에 1예를 보고하는 바이다.
Abstract
A 53 year-old woman presented with intermittent dizziness and palpitation. She had received VVI type pacemaker due to complete AV block in 1990, and exchanged by VVIR type pacemaker thirteen years later. 1 year later, she suffered intermittent dizziness and palpitation in erect position, not in supine position. Intermittent pacing failure and sensing failure was observed in pacemaker test, especially in erect position, not in supine position. Pacing threshold was increased in erect position, but lead impedance was not changed. Insulation break was observed in bipolar lead by fluoroscope. Initially we tried a new lead implantation by cephalic access to prevent lead related complication, but failed. So, we implanted a new bipolar lead by subclavian access. Finally, she was treated by a new bipolar lead implantation.(Korean J Med 70:84-89, 2006)
