May support dual-sensor pacing for physiologic early exercise response; hypothesis-generating, needs RCTs before practice change.
Does dual sensor pacing improve exercise cardiac output compared to single sensor pacing in patients with pacemakers?
Dual sensor pacing provides a more physiological cardiac output response during exercise compared to single sensor pacing by optimizing the heart rate to workload relationship.
