| Popis: | Background and Objectives：It has been suggested that lead impedance measurements with using real-time telemetry may offer a good estimation of the lead system integrity, and the serial measurement of the pacing lead impedance over time is a useful tool to monitor the pacing lead performance. However, there has been no consistent data about the changes of lead impedance over time. Therefore, we investigated the correlation of the direct lead impedance and the telemetered lead impedance, and the changes of lead impedance over time in both the atrial and ventricular leads. Subjects and Methods：The direct and telemetered lead impedances were measured at the time of the initial implantation. One-hundred and five patients (mean age: 62.5±13.5 years, 47 males, 47 atrial leads and 105 ventricular leads) who were without lead failure for more than 4 years since the initial implantation were included in the study. Afterwards, the telemetered lead impedance was examined at 2-month and at 12-month after implantation and then annually for 4 years in all the patients at a pacemaker clinic. Results：At the initial implantation, the direct lead impedance and the telemetered lead impedance were 470.2±12.2Ω and 540.9±11.6Ω, respectively, in the atrial leads (r=0.72, p |
