Automatic external defibrillators (AEDs) have proven to be successful tools against sudden cardiac death since the 1970s. They operate on a simple premise--using a device with a built-in algorithm in a computer chip to "read" a persons's electrocardiogram (ECG) and, if necessary, advise or deliver a shock to bring the person back to a normal rhythm. When first introduced, these devices used various methods of collecting ECG's and detecting ventricular fibrillation (v fib) and ventricular tachycardia (v tach), two treatable dysrhythmias.
自20世纪70年代以来，自动体外除颤器（AED）已被证明是预防心源性猝死的成功工具。它们基于一个简单的原理运行——使用计算机芯片中内置算法的设备来“读取”人的心电图（ECG），并在必要时给出建议或施加电击，使患者恢复正常心律。最初推出时，这些设备使用了各种收集心电图以及检测室颤（v fib）和室性心动过速（v tach）这两种可治疗的心律失常的方法。
