室性快速性心律失常的射频消融术

治疗折返所致的室上性心动过速射频消融术（ＲＦＣＡ）已成为首选的治疗方法。然而，ＲＦＣＡ治疗室性快速性心律失常尚处于起步阶段，特发性室性心动过速治疗较为成功，而对于器质性心脏病室性心动过速和室性早搏则存在较大困难，成功率低，并发症多，易复发。只有通过改进标测技术和导管，寻找更大能扩大消融范围和增加消融深度的新能源，方能提高成功率。

Radiofrequency catheter ablation for treating ventricular tachycardia

Radiofrequency catheter ablatoin(RFCA) has become the first choice for treating reentry paroxysmal supraventricular tachycardia.However,treatment for ventricular tachycardia by RFCA is still at initial phases.Treatment for idiopathic ventricular tachycardia by RFCA is successful,but it is very difficult for organic ventricular tachycardia and ventricular premature beat.Because it's lower success rate,more complication and higher recurrence rate.Only by improving mapping methods and finding new energy which can expand range and increase depth for ablation,it can raise success rate.
