Abstract
5 patients (pts) with life-threatening ventricular techyarrhythmias (VF: 3pts, VT/VF; lpt, VT; lpt) underwent surgery of AICD. Implantation of AICD was indicated for patients who survived circulatory arrest due to documented VT and/or VF. The patient should be medically refractory or madical treatment precluded by hemodynamic instability; other surgical treatment should not be possible. In a operation, VT/VF were induced 1 to 6 times for the measurement of defibrillation threshold (DFT). In all our pts, the AICD appropriatly discharged at postoperative EPS and in 2 pts, it discharged appropriate shock for spontanious VT. As for complications, in 1 pt with severe LV dysfudction, inccesant form of VT/VF occured after DFT testing and LV assist circulation and IABP were needed. Inappropriate discharge was recognized in 2 pts and pericarditis in 2pts postoperatively. It was considered that this system was effective for the treatment of life-threatening ventricular techyarrhythmias. AICD, life-threatening ventricular tachyarrhythmia, ventricular fibrillation, ventricular tachycardia, sudden cardiac death.
