Key result
Cardiac fulcrum anatomy reveals AV node proximity and nervous plexus invasion, suggesting an electromechanical unit.
Why the study?
The study was conducted to describe and understand the interrelation between the cardiac fulcrum and the Aschoff-Tawara atrioventricular node.
Observational (n=31)
The anatomical proximity and neural interconnection between the cardiac fulcrum and the AV node suggest the existence of an electromechanical unit, providing a structural basis for improved pacing synchrony when stimulating the right ventricular outflow tract.
Animal histology links fulcrum to AV node; hypothesis-generating for electromechanical effects on RVOT pacing synchrony.

Trainini et al. (2023) conducted an observational in Cardiac anatomy (n=31). Anatomical and histological examination was evaluated on Anatomical and histological relationship between the cardiac fulcrum and the AV node. Anatomical and histological analysis demonstrated that the cardiac fulcrum is adjacent to the atrioventricular node and invaded by a nervous plexus, suggesting an electromechanical unit.
