Enables chronic conduction system studies in canines; leaves open human translation.
Endocardial electrodes can safely record the electrical activity of the specialized conducting system in canine hearts without causing injury, enabling chronic studies.
Hoffman et al. (1960) studied this question. In situ endocardial electrode recording was evaluated on Sequence of activation of the specialized conducting system. In situ endocardial electrode recording in canine hearts successfully mapped the sequence of activation of the specialized conducting system without causing injury at the recording site.
