Temporary epicardial pacing wires are reliable for short-term use after open heart surgery, though their electrical performance deteriorates daily and cannot be predicted by perioperative factors.
Elmi et al. (2002) conducted a cohort in Open heart surgery (n=60). Temporary epicardial pacing wires was evaluated on Capture threshold, electrogram amplitude and slew rate, and lead impedance (p=<0.001). Temporary epicardial pacing wire function deteriorated daily after open heart surgery, with atrial and ventricular thresholds increasing significantly by the 4th postoperative day (p<0.001).
