Enables human intracardiac EP recordings; leaves open standardization and outcome data before routine adoption.
Observational
Demonstrates the feasibility of recording specialized conducting fibers in humans using an electrode catheter, foundational for clinical cardiac electrophysiology.
Damato et al. (1969) conducted an observational in Cardiac conduction. Electrode cardiac catheter recording was evaluated on Extracellular action potentials of the A-V node, His bundle, and right bundle branch. An electrode cardiac catheter positioned across the tricuspid valve successfully recorded extracellular action potentials of the A-V node, His bundle, and right bundle branch in human subjects.
