Wm. Miles et al., ELIMINATION OF AV NODAL REENTRANT TACHYCARDIA WITH 2 1 VA BLOCK BY POSTEROSEPTAL ABLATION/, Journal of cardiovascular electrophysiology, 5(6), 1994, pp. 510-516
AV nodal reentry capable of VA block during tachycardia was successful
ly eliminated using a posteroseptal ablation pulse delivered well away
from the site of earliest atrial activation during tachycardia. A pos
sible explanation is that the arrhythmia represented typical AV nodal
reentrant tachycardia with transient intra-atrial conduction block dur
ing tachycardia.
