Rs. Damle et al., RADIOFREQUENCY CATHETER ABLATION OF IDIOPATHIC LEFT-VENTRICULAR TACHYCARDIA ORIGINATING IN THE LEFT ANTERIOR FASCICLE, PACE, 21(5), 1998, pp. 1155-1158
Radiofrequency catheter ablation has been used to treat idiopathic lef
t ventricular tachycardia with high success rates. The majority of rep
orted cases have exhibited the typical findings of right bundle branch
block morphology with left axis deviation and originate from within o
r near the left posterior fascicle. We report a case of idiopathic lef
t ventricular tachycardia originating from within or near the left ant
erior fascicle, which was successfully ablated using a local Purkinje
potential as a guide.
