K. Kondo et al., Radiofrequency catheter ablation of ventricular tachycardia from the anterobasal left ventricle, JPN HEART J, 41(2), 2000, pp. 215-225
Ventricular tachycardia (VT) in coronary artery disease arises mostly from
endocardial sites. However, little is known about the site of origin in oth
er diseases. We report two patients who had VT originating from an anterior
aspect of the left ventricle just below the mitral annulus, adjacent to th
e left ventricular outflow tract. The QRS configuration of VT showed an inf
erior axis and monophasic R waves in all the precordial leads. Radiofrequen
cy current delivered to this site from the endocardial site successfully ab
lated the tachycardia in both.
