Idiopathic left ventricular tachycardia is a distinct clinical entity with a typical ECG of right bundle branch block and left axis deviation. We presented a 39-year-old man with idiopathic left ventricular tachycardia, which demonstrated change in the configuration of QRS complex during successive radiofrequency catheter ablation. We proposed that this idiopathic left ventricular tachycardia may have alternative pathways within the reentrant circuit leading to different exits.
特发性左心室心动过速是一种独特的临床实体，具有典型的右束支传导阻滞和左轴偏移心电图表现。我们报告了一名39岁的特发性左心室心动过速男性患者，在连续的射频导管消融过程中，其QRS波群形态发生了变化。我们提出，这种特发性左心室心动过速可能在折返环内有不同的传导途径，从而导致不同的出口。
