本文通过对12例永久人工心脏起搏病人的观察,初步探讨了起搏导管电压阈值随时间变化的规律性。在初安起搏器后4～6个月其阈值升高为首次起搏阈值的一倍;10～12个月达到峰值,为首次起搏阈值的1.2倍;以后随着时间的延长,阈值逐渐下降,至25～36个月稳定在略高于首次起搏阈值的水平。对于安装永久人工心脏起搏时,起搏导管的位置,起搏阈值的调整,安装起搏器的注意事项进行了讨论。
In this paper, 12 cases of permanent artificial cardiac pacing were observed, and the regularity of pacing catheter voltage threshold with time was initially discussed. In the first Pacemaker 4 to 6 months after the threshold increased for the first time the pacing threshold of doubling; 10 to 12 months to reach the peak, the first pacing threshold of 1.2 times; later with the extension of time, the threshold Gradually decreased to 25-36 months stabilized slightly higher than the level of the first pacing threshold. Positioning of pacing catheters, adjustment of pacing thresholds, and precautions for installing pacemakers are discussed when installing permanent artificial cardiac pacing.
