This study compares three different pacing system analyzers, which measure impedance at different points during an impulse, with measurements telemetered from implanted pacemakers from four different manufacturers. Measurements were obtained at the time of implantation in a group of 103 patients. The measurements obtained by these different methods differ significantly from each other; the later during the impulse the impedance is measured, the higher in general its value. Interpretation of impedance values should take into account the technique of measurement.
本研究比较了三种不同的起搏系统分析仪，它们在冲动期间的不同时间点测量阻抗，并与来自四个不同制造商的植入式起搏器遥测的测量值进行比较。在一组103名患者植入时获取测量值。通过这些不同方法获得的测量值彼此之间存在显著差异；在冲动期间测量阻抗的时间越晚，其值通常越高。阻抗值的解释应考虑测量技术。
