Temporary inhibition of permanently implanted demand pacemakers has been previously described. Demand pacemakers may be inhibited by waving a magnet over the region of the pacemaker generator or by chest wall stimulation. The former may not inhibit most of the bipolar pacemakers, whereas the latter may be time consuming and may casue patient discomfort. Another method is described which utilized a commercially available Cordis Omnicor Programmer, Model 166-B, to temporarily inhibit bipolar and unipolar pacemakers. By placing the programmer over the skin where the pacemaker generator is implanted and/or over the area of the subcutaneous pervenous lead and activating the programmer multiple times at a rate faster then the pacing rate, the demand pacemakers are inhibited. After testing the efficacy in vitro, the method was successfully tried on 45 patients. Fifteen of these patients had unipolar pacemakers. Pacemakers marketed by Medtronic, Cordis, Starr-Edwards, C.P.I., and Arco were tested. Temporary inhibition of permanent demand pacemakers is desirable under various clinical situations. The method herein described has the advantages of being simple, quick, painless, and is effective for both unipolar and bipolar pacemakers.
先前已有关于永久植入式按需起搏器的临时抑制的描述。按需起搏器可通过在起搏器发生器区域上方挥动磁铁或通过胸壁刺激来抑制。前者可能无法抑制大多数双极起搏器，而后者可能耗时且会引起患者不适。本文描述了另一种方法，该方法利用市售的Cordis Omnicor编程器（型号166 - B）来临时抑制双极和单极起搏器。通过将编程器放置在植入起搏器发生器的皮肤上方和/或皮下静脉导线区域上方，并以高于起搏频率的速率多次激活编程器，按需起搏器被抑制。在体外测试了该方法的有效性后，在45例患者身上成功进行了尝试。这些患者中有15例拥有单极起搏器。对美敦力、Cordis、斯塔尔 - 爱德华兹、C.P.I.和阿科公司销售的起搏器进行了测试。在各种临床情况下，永久按需起搏器的临时抑制都是可取的。本文所述方法具有简单、快速、无痛的优点，并且对单极和双极起搏器均有效。
