Combined electrode pores plus platinum-iridium coating may enable lower-output pacing; extends prior single-feature optimization trials with 2-year RCT evidence.
Do small changes in pacing electrode design, such as platinum-iridium coating and laser pores, reduce threshold voltages in patients requiring pacemakers?
Combining laser pores with a platinum-iridium coating on pacing electrodes significantly reduces threshold voltages over 2 years compared to either design feature alone.
