Supports steroid-eluting leads for lower chronic thresholds; leaves open randomized confirmation before changing electrode selection.
Do porous steroid-eluting electrodes improve pacing thresholds compared to platinized grooved electrodes in patients receiving unipolar leads?
Steroid-eluting electrodes provide significantly lower chronic pacing thresholds compared to platinized electrodes, allowing for safe pacing at reduced outputs.
