QRS alternans during idiopathic ventricular tachycardia originating from the right coronary cusp of the aorta
Europace, 11/10/2009
|
Yamada T et al. – A 77–year–old man underwent electrophysiological testing for idiopathic ventricular tachycardia (VT) with QRS alternans exhibiting a left bundle branch ... catheter ablation was achieved at the site of the earliest ventricular activation in the right coronary cusp. Pacing at this site reproduced an excellent pace map with QRS alternans. Pacing from other sites in the ventricular outflow tracts reproduced neither an excellent pace map nor QRS alternans ... multiple exits in the aortic root may exhibit QRS alternans.

Arrhythmias originating from the right ventricular outflow tract: How to distinguish “malignant” from “benign
Heart Rhythm, 10/05/2009
|
Shimizu W – In this review article, previous reports describing the malignant form of idiopathic RVOT VT are reviewed, and it is discussed how to distinguish the malignant form from ... the “benign” form of idiopathic VT originating from the RVOT.
