We describe in this report an unusual form of Wenckebach upper rate response produced by a DDD pulse generator with atrial-based lower rate timing. The pacemaker maintained the programmed upper and lower rate intervals at the expense of a prolonged atrial paced-ventricular paced AV interval. This form of upper rate behavior eliminated the longer cycle (containing the unsensed P wave) that occurs at the end of the pacemaker Wenckebach sequence during traditional DDD pacing with ventricular-based lower rate timing.
我们在本报告中描述了一种由具有心房基础下限频率计时功能的DDD脉冲发生器产生的不寻常的文氏型上限频率反应形式。起搏器以延长心房起搏-心室起搏的房室间期为代价维持设定的上限和下限频率间期。这种上限频率行为形式消除了在传统基于心室下限频率计时的DDD起搏过程中起搏器文氏序列末端出现的较长周期（包含未感知到的P波）。
