Thirty-five patients were randomized to receive either the Medtronic 6500 or one of two braided multifilament temporary pacing leads in the atrium following open heart surgery. Sensing performance was judged by amplitude, slew rate, and the proportion of patients with an adequate sensing threshold. Pacing performance was assessed with measures of impedance, threshold voltage, current, and energy. The Medtronic 6500 demonstrated superior sensing and lower energy consumption compared to braided multifilament leads. This type of lead may offer advantages when using atrial synchronous temporary pacing systems.
35名患者在心脏直视手术后被随机分配，分别接受美敦力6500型起搏器或两种编织多丝临时心房起搏导线中的一种。通过振幅、 slew速率以及感知阈值合适的患者比例来判断感知性能。通过阻抗、阈值电压、电流和能量测量来评估起搏性能。与编织多丝导线相比，美敦力6500型起搏器表现出卓越的感知能力和更低的能耗。在使用心房同步临时起搏系统时，这种类型的导线可能具有优势。
