Why the study?

Does VVIR pacing improve exercise capacity and quality of life compared to VVI pacing in pacemaker dependent patients?

Population

12 pacemaker dependent patients with VVIR units

Comparison

VVIR pacing (rate responsive pacing) vs VVI pacing

Design

Single blind

Implication

VVIR may improve exercise capacity and symptoms versus VVI; leaves open whether daily activity increases in pacemaker-dependent patients.

Structured PICO

Does VVIR pacing improve exercise capacity and quality of life compared to VVI pacing in pacemaker dependent patients?

Population

12 pacemaker dependent patients with VVIR units

Intervention

VVIR pacing (rate responsive pacing)

Comparator

VVI pacing

Outcome

Exercise capacity assessed by treadmill tests (modified Bruce protocol and a fixed workload protocol) with respiratory gas analysissurrogate

VVIR pacing improves treadmill exercise capacity and quality of life compared to VVI pacing, but does not appear to increase daily activity levels measured by pedometers.
