The procedural success in the implantation of cardiac electric devices depends on both the implanted position and the electric performance. The capture threshold and the pacing output affect the estimated battery longevity. In a case with a high capture threshold, recapture and reimplantation of a leadless pacemaker are commonly recommended. We experienced a case with the rate-dependent elevation of the capture threshold following the implantation of a leadless pacemaker. The recognition of the rate-dependency of the capture threshold and the acceptable programming could avoid the unnecessary recapture and reimplantation of that, avoiding the increase of procedural risks.
心脏电子设备的植入程序的成功取决于植入位置和电性能。捕获阈值和起搏输出会影响电池寿命的估计。在捕获阈值较高的情况下，通常建议重新捕获和重新植入无导线起搏器。我们遇到了一例在植入无导线起搏器后捕获阈值随频率依赖性升高的病例。识别捕获阈值的频率依赖性和可接受的程控可以避免不必要的重新捕获和重新植入，从而避免程序风险的增加。
