Initial Experience with a New Single Chamber, Dual Sensor Rate Responsive Pacemaker
Why the study?
Does a dual sensor rate responsive pacemaker provide adequate sensing and appropriate pacing rate response compared to single sensor mode?
Population
90 patients receiving a new single chamber, dual sensor rate responsive pacemaker across 21 centers
Comparison
Dual sensor rate responsive pacing mode vs Activity-Only pacing mode

Implication
Dual-sensor pacing may yield more physiological rates; leaves open outcome benefits versus single-sensor modes in larger studies.
Structured PICO
Does a dual sensor rate responsive pacemaker provide adequate sensing and appropriate pacing rate response compared to single sensor mode?
P
Population
90 patients receiving a new single chamber, dual sensor rate responsive pacemaker across 21 centers
I
Intervention
Dual sensor rate responsive pacing mode (activity and stimulus-to-T wave interval)
C
Comparator
Activity-Only pacing mode (assessed in a subgroup of 15 patients during exercise testing)
O
Outcome
Device sensing adequacy and pacing rate response during exercise and daily activitiessurrogate
Initial experience with a dual sensor rate responsive pacemaker demonstrates adequate sensing and a more physiological pacing rate response compared to single sensor devices.
