摘要：

Left Ventricular Outflow Tract Tachycardia, Idiopathic ventricular tachycardia (VT) originating from the left ventricular outflow tract (LVOT) is rare, We report two patients whose QRS configuration during VT commonly showed an inferior axis and monophasic R waves in all the precordial leads. The mechanism of these VTs appeared to be triggered activity. From mapping and ablation, the origin of these VTs was determined to be in the most posterior LVOT, corresponding to the aortomitral continuity (left fibrous trigone).
