目前,绝大多数心律失常可以通过抗心律失常药物、抗心动过速起搏器和除颤器、经导管电消融以及外科手术加以控制。而外科手术和经导管电消融是目前可以直接破坏或隔离心律失常起源灶,治愈心律失常的方法。然而,并非所有病人都能承受外科手术的治疗。此外,由于外科手术本身对心脏的严重损伤可导致较高的手术死亡率。而经导管电消融治疗心律失常虽然可以避免开胸手术,但其治疗室性心动过速(简称室速)的成功率太低,其原因是经导管精确的标测和定位室性异位兴奋灶非常困难,因而很难准确地选择电击点进行有效的消融。另外,经 Currently, the vast majority of arrhythmias can be controlled by anti-arrhythmic drugs, anti-tachycardia pacemakers and defibrillators, catheter ablation, and surgery. Surgical and transcatheter electrical ablation is the method that can directly destroy or isolate the origin of arrhythmia and cure arrhythmia. However, not all patients can be treated surgically. In addition, severe surgical injury to the heart due to surgery can result in higher operative mortality. While the treatment of cardiac arrhythmia by catheter ablation can avoid thoracotomy, but its success rate of treatment of ventricular tachycardia (VT) is too low, because of catheter accurate mapping and positioning of ventricular ectopic excitability The stove is so difficult that it is difficult to select the point of shock for effective ablation. In addition, after
