Prevention of Atrial Arrhythmias during DDD Pacing by Atrial Overdrive
Why the study?
Does atrial overdrive pacing reduce the incidence and burden of atrial arrhythmias in patients with DDD pacemakers?
Population
22 patients with Chorus 6234 DDD pacemakers, mean age 67 +/- 9 years, 7 women and 15 men.
Comparison
Atrial overdrive for 1 month. vs Baseline pacing with lower rate programmed to 55…
Design
Cohort
Follow-up
3 months (three phases of 1 month each)

Overview
May reduce AA burden with atrial overdrive in DDD pacemakers; leaves open need for randomized confirmation.
Structured PICO
Does atrial overdrive pacing reduce the incidence and burden of atrial arrhythmias in patients with DDD pacemakers?
P
Population
22 patients with Chorus 6234 DDD pacemakers, mean age 67 +/- 9 years, 7 women and 15 men.
I
Intervention
Atrial overdrive (programmed paced rate 10 ppm faster than the mean ventricular rate stored for the last 24-hour period in the pacemaker memory) for 1 month.
C
Comparator
Baseline pacing with lower rate programmed to 55 ppm for 1 month.
O
Outcome
Incidence of atrial arrhythmias (AA), number and maximal duration of AA episodes, and total AA time in a month.surrogate
Atrial overdrive pacing significantly reduces the incidence and burden of atrial arrhythmias in patients with DDD pacemakers over a short-term period.
Limitations
- Short-term data
