摘要

The subcutaneous implantable cardioverter defibrillator (S-ICD) has become an alternative to the transvenous ICD in indicated patients.However, inappropriate shock or failed ventricular tachycardia/fibrillation conversion is the most alarming complication of S-ICD.Therefore, defibrillation test (DFT) is recommended for the S-ICD implantation.However, the DFT can provoke or worsen cardiac arrhythmias.We present two induced atrial fibrillation (AF) cases by DC bursts on DFT during S-ICD implantation.The AF was not terminated by the 65-J S-ICD shock, even when ventricular fibrillation was terminated.
