We studied the occurrence and characteristics of crosstalk related to the atrial sense marker function of the Intermedics Cosmos DDD pulse generator in 29 patients. Upon activation of the atrial sense markers, the pulse generator delivers a series of markers in the form of triggered atrial stimuli at 0.025 ms in duration at the programmed voltage output of the atrial channel. Under certain circumstances, these atrial sense marker stimuli may cause crosstalk when they are sensed by the ventricular sensing amplifier. This form of crosstalk may be eliminated in most cases by decreasing ventricular sensitivity and/or atrial output voltage.
我们研究了29例患者中与Intermedics Cosmos DDD脉冲发生器心房感知标记功能相关的串扰的发生情况及特征。在激活心房感知标记时,脉冲发生器会以触发心房刺激的形式在心房通道的程控电压输出下以0.025毫秒的持续时间发送一系列标记。在某些情况下,当这些心房感知标记刺激被心室感知放大器感知到时,可能会引起串扰。在大多数情况下,通过降低心室灵敏度和/或心房输出电压可以消除这种串扰形式。
