The human intrinsic cardiac nervous system is more extensively distributed than previously thought, with complex microscopic synaptology.
Ganglion mapping should not yet guide interventions; leaves open their roles in autonomic regulation and disease.
The human intrinsic cardiac nervous system is distributed more extensively than was considered previously, most of its ganglia being located on the posterior surfaces of the atria and superior aspect of the ventricles. Each ganglion therein contains a variety of neurons that are associated with complex synaptology.
