摘要

起搏阈值对无引线起搏器非常重要，因为起搏输出量对电池寿命有重大影响。无导联起搏器也有急性起搏速率依赖性阈值升高的报道。在本病例中，我们经历了这样一个病例：急性期阈值升高后，阈值一度出现改善趋势，但随后又再次恶化。与之前的报告一样，阈值在慢性期完全改善。反复取回和重新植入无引线心脏起搏器会增加致命并发症的可能性，因此注意这种现象可以避免不必要的手术和并发症。

A case of repeated rate-dependent pacing threshold elevation after leadless pacemaker implantation.

The pacing threshold is important for leadless pacemakers, as the pacing output has a significant impact on battery longevity. Acute pacing rate-dependent threshold increases have also been reported with leadless pacemakers. In the present case, we experienced a case in which the threshold, which had been raised in the acute phase, once showed a tendency to improve, but then worsened again. And, as in previous reports, thresholds improved completely in the chronic phase. Repeated retrieval and reimplantation of leadless pacemakers increases the likelihood of fatal complications, so being aware of such phenomenon may prevent unnecessary procedure and complications.
