Implication
Identifies posterior slow pathway as retrograde limb in post-modification atypical AVJRT; hypothesis-generating for targeted ablation, needs confirmation.
Structured PICO
P
Population
6 patients undergoing radiofrequency current catheter modification of the AV node who had inducible atypical atrioventricular junctional reentrant tachycardia (AVJRT) before or after AV nodal modification.
I
Intervention
Radiofrequency catheter modification of the AV node (anterior approach)
O
Outcome
Electrophysiological characteristics including AH intervals, AH/HA ratios, and retrograde atrial activationsurrogate
The retrograde limb of atypical AVJRT seen following anterior approach AV nodal modification is a posterior, slow pathway.
