The availability of an automated external defibrillator (AED) can improve the outcome of patients with out-of-hospital cardiac arrest (OHCA). On June 1, 2000, Taipei City became the first city in Taiwan to equip emergency medical services personnel with AEDs. This study was conducted to assess the performance of the AED machine in detecting ventricular fibrillation (VF) and ventricular tachycardia (VT) in the population, and to assess operator performance in its use. ⋯ This study found that the AED machine has high specificity and high sensitivity in detecting VF and VT, especially coarse VF. Efforts are needed to improve the timing of AED deployment and emergency medical technician compliance with standard procedures.
