RVA pacing may impair LA function even at moderate burdens; leaves open whether alternative sites or minimized pacing improve outcomes in sick sinus syndrome.
Does right ventricular apical pacing impair left atrial function in patients with sick sinus syndrome?
Right ventricular apical pacing induces left ventricular dyssynchrony and significantly impairs left atrial function, with detrimental effects observed even at pacing burdens below 50%.
Choi et al. (2012) studied this question.
