摘要 对117例安装不同品牌、型号起搏器的患者进行长期随访观察，探讨低能量起搏的安全性及程控计算方法。在安装起搏器2个月～12年后测定起搏阈值，结果为2.43±0.75 V、0.14±0.10 ms，同时将脉宽设置为阈值的2倍、3倍或更多。15例经1.1～4.3年的随访，再次重复测定阈值(8例增加、4例下降、3例不变)，并调整相应参数。117例患者的随访时间为1～6年，此间均未发现起搏失效。由此认为起搏阈值设置为能量阈值的3～4倍是安全的。

Abstract Various model pacemakers were implanted with 117 cases. The capture threshold was 2.43±0.75 V (pulse amplitude) and 0.14±0.10 ms (pulse width) after implanting for 2 months to 12 years. Then, The pulse width was set up two to three or more times of capture threshold. The capture threshold was measured repeatly after 1.1～ 4.3 years in 15 patients. No pacing failure was found in all patients in the following period. We recommed that a 3～ 4-fold margin of safety for capture is available based upon the deliveried pulse energy.
