Why the study?

Does AAI pacing improve clinical outcomes compared to DDD pacing in patients with sick sinus syndrome and normal AV conduction?

Population

196 age-matched patients with sick sinus syndrome (SSS) and normal atrioventricular (AV) conduction

Comparison

AAI pacing vs DDD pacing (dual-chamber pacemaker)

Design

Cohort

Follow-up

10 years

Overview

AAI pacing was associated with similar outcomes and fewer lead failures than DDD in sick sinus syndrome; leaves open need for randomized confirmation before practice change.

Structured PICO

Does AAI pacing improve clinical outcomes compared to DDD pacing in patients with sick sinus syndrome and normal AV conduction?

P
Population
196 age-matched patients with sick sinus syndrome (SSS) and normal atrioventricular (AV) conduction
I
Intervention
AAI pacing (single lead and single-chamber pacemaker)
C
Comparator
DDD pacing (dual-chamber pacemaker)
O
Outcome
Mortality, chronic atrial fibrillation, lead survival rates, and reoperation rateshard clinical

AAI pacing provides similar long-term clinical outcomes to DDD pacing in patients with sick sinus syndrome and normal AV conduction, while significantly reducing the risk of lead failure.
