Why the study?

Does consistent atrial overdrive pacing reduce premature atrial complexes and automatic mode switching in patients with sick sinus syndrome?

Population

15 patients with sick sinus syndrome implanted with a Thera DR pacemaker (model 7940 or 7960, Medtronic Inc.)

Comparison

Rate adaptive dual chamber pacing + consistent… vs Rate adaptive dual chamber pacing for an 8-week…

Design

RCT, randomly programmed

Follow-up

8 weeks per pacing mode

Overview

Consistent atrial pacing reduces premature atrial complexes without lowering mode switching episodes; challenges ectopy suppression as a strategy to reduce atrial tachyarrhythmia burden.

Structured PICO

Does consistent atrial overdrive pacing reduce premature atrial complexes and automatic mode switching in patients with sick sinus syndrome?

Population

15 patients with sick sinus syndrome implanted with a Thera DR pacemaker (model 7940 or 7960, Medtronic Inc.)

Intervention

Rate adaptive dual chamber pacing (DDDR) + consistent atrial pacing mode (automatically paced the atrium at 30 ms shorter than the sinus P-P interval) for an 8-week study period

Comparator

Rate adaptive dual chamber pacing (DDDR) for an 8-week study period

Outcome

Number of automatic mode switching episodes and number of premature atrial complexessurrogate

Consistent atrial overdrive pacing significantly reduces premature atrial complexes without increasing overall atrial rate, but does not significantly reduce automatic mode switching episodes.
