Supports lead selection flexibility by acute metrics; leaves open long-term outcome comparisons across designs.
Do different polarity and electrode designs impact acute pacing and sensing characteristics of pacemaker leads in patients undergoing pacemaker implantation?
Different pacemaker lead designs and polarities do not significantly affect acute pacing and sensing thresholds, though active fixation leads offer placement advantages.
