摘要

vdd -无导线起搏器旨在保持房室（AV）高度同步，但适当的传感设置至关重要。方法和结果：该病例是一名老年妇女，房室传导阻滞，接受双室起搏器。由于心室起搏衰竭，植入了一个Micra AV2。然而，植入后，窦性窦率高，室性早搏频繁。因此，在心房传感设置中使用auto + A3阈值函数。几天后，MAM测试证实了良好的AV同步。结论：Micra AV2配备auto + A3阈值功能可能有助于维持高AV同步性。

Utility of the Novel Auto + A3 Threshold Function in Maintaining Atrioventricular Synchrony.

Introduction: The VDD-leadless pacemaker aims to maintain high atrioventricular (AV) synchrony, but proper sensing setup is crucial.

Methods and results: This case was an elderly woman with an AV block who received a dual-chamber pacemaker. Due to ventricular pacing failure, a Micra AV2 was implanted. However, postimplantation, high sinus rate, and frequent premature ventricular contractions were noted. Therefore, the auto + A3 threshold function was used in the atrial-sensing setup. A few days later, the MAM test confirmed good AV synchrony.

Conclusion: The auto + A3 threshold function equipped in the Micra AV2 may offer to maintain high AV synchrony.
