本文研究经静脉导管用体外复律除颤器治疗自发性室性心律失常.对象及方法:急性心肌梗塞后或术后恶性心律失常患者17(男11、女6)例,年龄46—75岁,均有复发性室性心动过速(VT)及/或室颇(Vf).经静脉置入四极导管,最远端电极置右室心尖部,次远端电极与之相距5mm 而组成复律的阴极对.并充作同步复律的感知及心室起搏的电极对.最近端电极置上腔静脉与右房交界处,次近端电极与之组成复律阳极对,相距亦为5mm.每对电极合并
In this paper, venous catheter with external cardioverter defibrillator treatment of spontaneous ventricular arrhythmias.Methods: 17 (11 males and 6 females) patients aged 46-75 years after acute myocardial infarction or postoperative malignant arrhythmia , Both with recurrent ventricular tachycardia (VT) and / or ventricular reserve (Vf) .After intravenous placement of a quadrupole catheter, the most distal electrode was placed right ventricular apex, and the second distal electrode was separated by 5 mm Cardioversion of the cathode, and as a synchronous cardioversion and ventricular pacing electrode pair.The proximal electrode placed near the junction of the superior vena cava and the right atrium, the second electrode and the proximal electrode composed of complex anodes, 5mm. Each pair of electrodes combined
