报道射频消融治疗２例特发性左室室性心动过速的临床结果。心动过速形态均表现为右束支阻滞伴电轴左偏。心内标测显示心动过速起源于左室间隔的后下部和后中部。以心动过速的最早激动部位为消融靶点，分别放电７次和９次后心动过速不再诱发。有效消融靶点除室波明显超前ＱＲＳ波外．其室波前均有一高频低幅锐波，该波的性质尚不明确，可能代表“病变心肌”的激动波。
Reported radiofrequency ablation in 2 cases of idiopathic left ventricular tachycardia clinical results. Tachycardia manifested as right bundle branch block with left axis deviation. Intracardiac mapping shows that tachycardia originates in the posterior and posterior middle of the left ventricular septum. The earliest tachycardia excited part of the site as the ablation target, were discharged 7 times and 9 times after tachycardia was no longer induced. In addition to effective ablation of ventricular waves significantly ahead of QRS wave. The chamber wavefront has a high frequency low amplitude sharp wave, the nature of the wave is not yet clear, may represent “diseased myocardium” excited wave.
