An automatic external defibrillator (AED) was used by paramedics to detect ventricular fibrillation and deliver countershocks in 39 people with out-of-hospital cardiac arrests. The AED identified and delivered at least 1 countershock to 13 of the 16 people in ventricular fibrillation (81% sensitivity). The AED responded correctly to all 21 of the non-ventricular-fibrillation rhythms (8 other electrical rhythms, 13 asystole) with no countershocks (100% specificity). In 2 patients the rhythm could not be assessed. The device caused no injuries to patients or personnel. The performance of the AED was also analysed by considering each 15 s segment of ventricular fibrillation as a separate challenge; the device delivered a countershock in 19 of 29 such segments (66%).
护理人员使用自动体外除颤器（AED）对39例院外心脏骤停患者进行室颤检测并实施电击除颤。AED对16例室颤患者中的13例识别并至少实施了1次电击除颤（敏感性81%）。AED对所有21种非室颤心律（8种其他电节律、13种心脏停搏）均正确识别且未实施电击除颤（特异性100%）。2例患者的心律无法评估。该设备未对患者或人员造成伤害。通过将室颤的每15秒时间段视为一个单独的挑战来分析AED的性能；在29个这样的时间段中，该设备在19个时间段实施了电击除颤（66%）。
