Abstract
We experienced three cases of implantation of automatic implantable cardioverter defibrillator in patients with ventricular tachyarrhythmias. (VT; 1, VT+VF; 1, idiopathic VF; 1) One patient suffered from broad anterior myocardial infarction and another dilated cardiomyopathy. Implantation of AICD was indicated for patients who survived circulatory arrest or with life-threatening VT. In all cases median sternotomy was performed. Myocardial electrodes for sensory and large patch-small patch electrodes for defibrillation were selected. One case of moderate cardiac failure which needs intensive care and one case of pericarditis occurred as perioperative complication. In the follow-up period, AICD worked effectively in a patient of spontaneous VF 6 months after implantation. It is concluded that AICD system is effective for the life-threatening ventricular tachyarrhythmias although the estimation in longer follow-up period should be warrented.
