Does dual-chamber pacing improve quality of life and clinical outcomes in elderly patients compared with ventricular pacing?
Dual-chamber pacing provides quality-of-life benefits over ventricular pacing primarily in patients with sinus-node dysfunction.
The implantation of a permanent pacemaker improves health-related quality of life. However, the quality-of-life benefits associated with dual-chamber pacing as compared with ventricular pacing are observed principally in the subgroup of patients with sinus-node dysfunction.
Lamas et al. (Thu,) studied this question.
