方法 连续101例曾由室速和/或室颤引起晕厥的病人,正电极(Medtronic 6966型)固定于右室心关,负电极(Medtronic 7219型)埋置于左侧锁骨下囊袋内,发放倾斜65％的双向脉冲。测试前,停用标准抗快速性心律失常药物至少5个半衰期,停用胺碘酮1～2周。测试中,能够终止室颤的最小脉冲振幅作为除颤阈值(DFT)。
Methods A total of 101 consecutive patients with syncope caused by ventricular tachycardia and / or ventricular fibrillation were fixed with a positive electrode (Medtronic 6966) in the right ventricle and a negative electrode (Medtronic 7219) in the left subclavian sac. Deliver a bi-directional pulse of 65% tilt. Before testing, disable standard anti-tachyarrhythmia drugs for at least 5 half-lives and discontinue amiodarone for 1 to 2 weeks. In the test, the minimum pulse amplitude of ventricular fibrillation can be terminated as the defibrillation threshold (DFT).
