Ventricular fibrillation (VF) is the primary arrhythmia in majority of patients suffering from sudden cardiac attacks that has been focused on particular rhythm. In earlier stage an electrical defibrillator was utilized to treat the sudden cardiac attack with monophasic pulse. This pulse distributes energy to the patient’s heart in only one direction. Thus the tissues of the body will be affected more. AED is a device which analysis the VF rhythm from the normal rhythm and distributes a shock to the patient heart with sudden cardiac attack. AED is when utilized in biphasic pulse for distributing shock to a patient so the tissues of the body will not be affected like monophasic pulse. The simulation tools used are Keil μ vision, proteus8 (ISIS), Cadence orcad capture 16.3, progisp172, Microsoft visio office 2007, Mentor graphics PADS layout 9.2. AED prototypes are mostly adopted in public places like hospitals, Malls, shops, which avail to restore patient’s normal life.
