Atrial nerve ending maps extend neuroanatomy; leaves open functional roles in arrhythmias.
Observational (n=12)
This anatomical study describes two distinct types of nerve endings in the human endocardium, suggesting sensory and potential baroreceptor functions.
Brian Johnston (1968) reported an observational. Methylene blue perfusion was evaluated on Identification of nerve endings in the human endocardium. Methylene blue perfusion of 12 human hearts revealed two major types of nerve endings in the endocardium: complex unencapsulated endings and end-nets.
