May warrant closer threshold surveillance for high-risk epicardial leads; leaves open need for prospective validation.
What is the long-term risk of exit block with steroid-eluting ventricular epicardial pacing leads?
A 4-week postimplant pacing threshold >= 0.12 ms (5 V) with steroid-eluting epicardial leads predicts a significant long-term risk of exit block, warranting frequent threshold testing.
Beder et al. (1997) studied this question.
