摘要

导言：导致双腔起搏器心房传感不足的原因包括真正的传感不足（低振幅电图）、功能性传感不足（在信号充足的情况下与特殊定时周期的影响有关）和矛盾性传感不足。本病例报告描述了在较高的编程心房灵敏度下出现的矛盾性心房感应不足，以及在较低的编程灵敏度下恢复正常的心房感应。

Paradoxical under-sensing of atrial lead at high sensitivity setting in dual chamber pacemaker during atrial flutter - What is the mechanism?

Introduction: The causes of atrial undersensing in a dual chamber pacemaker include true undersensing (low amplitude electrogram), functional undersensing (related to the effect of special timing cycles in the presence of an adequate signal) and paradoxical undersensing. This case report describes paradoxical atrial undersensing at a higher programmed atrial sensitivity and with the return of normal atrial sensing at a lower programmed sensitivity.
