The aim is to report case 1 in which the first responder revives the patient by carrying out CPR for patients suffering from cardiac arrest and implementing fast defibrillation on site. This study placed consideration based on an interview and submitted medical records, by obtaining the consent of the ambulance worker arriving at the scene and the patient. The patient received a cardiac massage by the first responser, was monitored after the ambulance worker who was mobilized attached a defibrillation patch, and the rhythm of ventricular fibrillation was shown. The patient was then moved to the ambulance after returning to normal sinus rhythm following two shocks of 150 J. After being transferred to another hospital on the 15th day from when the accident occurred, the patient is returning to a normal life by returning home and to society (workplace). To increase the survival rate on patients with cardiac arrest prior to hospital, it is necessary for providing education and publicity to the general public in order to be possibly active in fast requests for aid, early access of emergency medical systems, early CPR, early defibrillation by eyewitness, and chain of survival in early advanced cardiac life support (ACLS). Indirect medical guidance needs to be vitalized so that the emergency medical technician can carry out professional treatment.
