Does endocardial electrode design affect polarization signals and the functional rate of the Autocapture algorithm in patients receiving pacemakers?
Absolute Event Rate: 91.7% vs 0%
Titanium nitride-coated ventricular electrodes provide lower polarization signals, making them more suitable for pacemaker algorithms based on evoked response detection like Autocapture.
Lau et al. (2001) conducted an observational in Pacemaker indication (primarily Sick Sinus Syndrome) (n=217). Titanium nitride (TiN)-coated electrodes vs. Platinum helix (PH) and other electrode designs was evaluated on Functional rate of Autocapture (AC). Titanium nitride-coated electrodes provided significantly lower polarization signals and a higher functional rate of Autocapture (91.7%) compared to platinum helix electrodes (0%).
