Key result
Direct guidance of His bundle pacing by electroanatomic mapping allowed reproducible navigation, with the atrial/ventricular ratio correlating with His cloud location (P=0.045).
Why the study?
His bundle pacing remains technically challenging under guidance by electrograms and 2-dimensional fluoroscopy, prompting the description of a new technique directly guided by electroanatomic mapping.
Does direct guidance by 3-dimensional electroanatomic mapping allow for reproducible His bundle pacing lead placement in patients requiring pacing?
Observational (n=28)
Does direct guidance by 3-dimensional electroanatomic mapping allow for reproducible His bundle pacing lead placement in patients requiring pacing?
p-value: p=0.045
Direct guidance of His bundle pacing by 3-dimensional electroanatomic mapping is feasible and allows for direct visualization and reproducible navigation to predetermined capture sites.

May support EAM-guided His bundle pacing navigation in select cases; hypothesis-generating and leaves open prospective validation.
Orlov et al. (2019) conducted an observational in Patients undergoing His bundle pacing (n=28). His bundle pacing guided by 3-dimensional electroanatomic mapping was evaluated on Correlation of intracardiac electrograms atrial/ventricular ratio at lead deployment site with EAM position on the His cloud (p=0.045). Direct guidance of His bundle pacing by electroanatomic mapping allowed reproducible navigation, with the atrial/ventricular ratio correlating with His cloud location (P=0.045).
