Why the study?
What are the conditions for successful radiofrequency catheter ablation of the atrioventricular junction to create complete AV block in a canine model?
What are the conditions for successful radiofrequency catheter ablation of the atrioventricular junction to create complete AV block in a canine model?
This preclinical study identified key electrophysiological and procedural parameters, including an A/V ratio ≥1.0 and accelerated junctional rhythm, for successful radiofrequency ablation of the AV junction.
Parameters from canine model may inform human AV junction ablation techniques; leaves open need for clinical validation.
