Minor pacing differences were noted. CPS Locator<jats:sup>TM<\/jats:sup> 3D performed similarly to C315His\u00ae delivery system with a trend for less lead placement attempts. Conduction system capture (CSC) pattern at implant did not differ between both groups. CSC maintenance was similar between SDL and LLL. However, follow\u2010up QRS duration was significantly longer in SDL group (154\u2009ms vs. 129\u2009ms, <jats:italic>p<\/jats:italic>\u2009=\u20090.004), suggesting a possibility of CSC loss in some patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>SDL is a viable alternative to LLL, demonstrating comparable acute and midterm pacing parameters.
