No electrode design yields superior thresholds; confirms equivalence among sintered platinum, vitreous carbon, and porous carbon leads.
Do different electrode designs (sintered platinum, vitreous carbon, porous carbon) for permanent cardiac pacing leads result in clinically demonstrable differences in electrical performance?
Differences between high-performance pacing leads with sintered platinum, vitreous carbon, or porous carbon electrodes do not provide a clinically significant advantage in electrical performance.
