A 68-year-old woman affected by sick sinus syndrome was implanted with a dual-chamber pacemaker provided by home monitoring technology. After discharge, an increase in ventricular threshold and a high variability of R wave measurements were detected early by the home monitoring system. Manual tests confirmed the presence of pacing and sensing failure and a normal ventricular impedance. The pacing lead integrity and a stable position of the lead tip in right ventricular apex were assessed by chest X-ray. A diagnosis of microdislodgement was made. After a second procedure for ventricular lead repositioning, no further malfunctions were detected.
一名68岁患病态窦房结综合征的女性植入了具备家庭监测技术的双腔起搏器。出院后，家庭监测系统早期检测到心室阈值升高以及R波测量值的高度变异性。手动测试证实存在起搏和感知故障以及正常的心室阻抗。通过胸部X光评估起搏导线的完整性以及导线尖端在右心室心尖的稳定位置。诊断为微脱位。在进行了第二次心室导线重新定位手术后，未再检测到故障。
