护理人员使用自动体外除颤器（AED）检测39例院外心脏骤停患者的心室颤动并给予反击。AED对16例心室颤动患者中的13例进行了识别并至少给予了1次反击（灵敏度为81%）。AED对所有21种非心室颤动节律（8种其他电节律，13种无骤停）均有正确反应，无反搏（100%特异性）。2例患者心律无法评估。该装置没有对患者或人员造成伤害。通过将每个15 s心室颤动段作为单独的挑战来分析AED的性能；该装置在29个这样的片段中有19个（66%）产生了反击。
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%).
