由于抗心律失常药物的副作用和致心律失常作用,80年代发展了介入性抗心律失常的治疗方法。导管消融术治疗原理:直流电消融术是指通过电极导管释放100～400J的能量,在极短时间内电压可达3000V,温度上升致数千度,造成局部组织球形损伤。损伤范围与所给能量有关,最大直径可达2cm。但由于直流电消融时产生气体和气压伤,可引 In the 1980s, interventional antiarrhythmic treatments were developed due to the side effects and arrhythmogenic effects of antiarrhythmic drugs. Catheter ablation treatment principle: DC ablation refers to the release of energy through the electrode catheter 100 ~ 400J, in a very short period of time the voltage up to 3000V, the temperature rise to thousands of degrees, resulting in local tissue spherical injury. Damage range and the energy given, the maximum diameter of up to 2cm. However, due to DC gas generated when the pressure and pressure injury, can lead
