Why the study?
Does electrical stimulation of parasympathetic nerve fibers in the epicardial fat pad near the sinoatrial node increase atrial cycle length in patients undergoing cardiac surgery?
Does electrical stimulation of parasympathetic nerve fibers in the epicardial fat pad near the sinoatrial node increase atrial cycle length in patients undergoing cardiac surgery?
Electrical stimulation of parasympathetic nerve fibers in a fat pad near the sinoatrial node selectively increases atrial cycle length without affecting AV nodal conduction in humans.

Supports selective SA-node parasympathetic stimulation for rate control; hypothesis-generating and requires prospective validation.
Carlson et al. (1992) studied this question.
