Threshold rise at 18-36 months may warrant closer surveillance; leaves open long-term durability of steroid-eluting leads in larger cohorts.
Steroid-eluting ventricular pacing electrodes demonstrate a significant increase in pacing threshold between 18 and 36 months post-implantation, but remain stable up to 5 years.
Stojanov et al. (1992) studied this question.
