直流电复律已广泛用于治疗室性心动过速(VT)、心室颤动(VF)和心房颤动(AF).最近已采用埋藏式去颤器并适用于院外的恶性室性心律失常患者.然而一次电击可能不足以终止VT和VF,即使在电击成功后亦可发生严重的心律失常.因此,必须了解VT和VF患者在自动直流电击后可能出 DC Cardioversion is widely used to treat ventricular tachycardia (VT), ventricular fibrillation (VF), and atrial fibrillation (AF). Recently, buried defibrillators have been used and are suitable for patients with malignant ventricular arrhythmias outside the hospital. A shock may not be enough to terminate VT and VF, even after a successful electrical shock, a serious arrhythmia can occur. Therefore, it is important to understand that patients with VT and VF may be present after an automatic DC shock
