摘要: A patient underwent radiofrequency (RF) catheter ablation for a drug-refractory ventricular tachycardia, but RF energy application at an endocardial site of the left outflow tract and sinus Valsalva could not eliminate tachycardia. The earliest activation during arrhythmia, which preceded onset QRS complex by 32 ms, was found within great cardiac vein complete elimination tachycardia finally achieved with that site.
