Key result
Catheter ablation of ATP-sensitive atrial tachycardias with earliest His bundle activation revealed successful sites at an average distance of 10.4 ± 8.8mm from the His bundle.
Why the study?
What is the spatial distribution of the origins of ATP-sensitive focal atrial tachycardias with earliest activation in the His bundle catheter?
Observational (n=12)
What is the spatial distribution of the origins of ATP-sensitive focal atrial tachycardias with earliest activation in the His bundle catheter?
Detailed mapping beyond the His bundle area is necessary when ablating ATP-sensitive atrial tachycardias with earliest activation recorded in the His bundle catheter, as the actual origin is often distant.
No takes yet. Share an insight, caveat, or question.
May warrant mapping beyond the His bundle in ATP-sensitive AT; case data leave optimal sites open.
Nakamura et al. (2012) conducted an observational in Adenosine triphosphate-sensitive focal atrial tachycardias (n=12). Catheter ablation was evaluated on Distance between the successful ablation site and the His bundle area. Catheter ablation of ATP-sensitive atrial tachycardias with earliest His bundle activation revealed successful sites at an average distance of 10.4 ± 8.8mm from the His bundle.
