Why the study?
Pacing from the apex of the RV is not considered optimal, leading to this assessment comparing RV and LV pacing concerning LV function and dyssynchrony.
Does left ventricular pacing improve LV function and dyssynchrony compared to right ventricular pacing in patients with indications for pacemakers?
Does left ventricular pacing improve LV function and dyssynchrony compared to right ventricular pacing in patients with indications for pacemakers?
Right ventricular apical pacing remains the standard for patients with normal or mildly impaired LV function (EF > 35%) requiring pacing, as it demonstrated less detrimental effects on LV synchrony and function in this study.
No takes yet. Share an insight, caveat, or question.
May favor LV over RV pacing to limit dyssynchrony; leaves open confirmation in randomized trials.
