Implication

Associated with higher survival in this cohort; leaves open whether DDD confers causal benefit over VVI.

Structured PICO

Do DDD pacemakers improve survival compared to VVI pacemakers in patients requiring pacing?

P
Population
666 patients receiving pacemakers at Mt. Sinai Medical Center, age range 28 to 103, mean age 78 years at time of implant.
I
Intervention
DDD pacemakers (received by 70% of the population)
C
Comparator
VVI pacemakers (received by 30% of the population)
O
Outcome
Survival incidence at 44 monthshard clinical

In a retrospective cohort, DDD pacemakers were associated with a higher 44-month survival incidence compared to VVI pacemakers, with manageable complication rates.
