The standard braided wire lead used for temporary pacing following open heart surgery may be rendered ineffective by high current thresholds. In this study braided leads were compared with a lead incorporating a localised stainless steel electrode in 17 patients undergoing routine cardiac surgical procedures. Each patient acted as his own control. The localised electrode lead gave significantly lower current and voltage thresholds compared to the braided lead, this difference being apparent both on the day of operation and prior to lead removal (p less than 0.0005). Use of a lead incorporating a localised electrode is therefore less likely to be restricted by difficulties in capture and sensing.
心脏直视手术后用于临时起搏的标准编织线电极可能会因高电流阈值而失效。在本研究中，对17例行常规心脏手术的患者使用的编织电极与带有局部不锈钢电极的电极进行了比较。每位患者均以自身作为对照。与编织电极相比，局部电极的电流和电压阈值显著更低，这种差异在手术当天和电极拔除前均很明显（p<0.0005）。因此，使用带有局部电极的电极受捕捉和感知困难限制的可能性较小。
