Technical Field

Background

Sudden cardiac death is the biggest threat facing mankind in this century and accounts for the vast majority of patients with sudden death. Epidemiological studies show that the incidence rate of sudden cardiac death outside 20-75 years old hospitals of European people is about 1 per thousand, and the incidence rate of sudden cardiac death outside American people is about 1 per thousand-2 per thousand. In the united states, approximately 40 to 46 million episodes of cardiac arrest occur outside the hospital each year; whereas, extrahospital sudden cardiac death occurs in about 80% of homes and 15% in streets and public places. Sudden death is the first manifestation of cardiovascular disease in most patients with extrahospital sudden cardiac arrest. The electric shock defibrillation and the cardio-pulmonary resuscitation can be found and shocked timely, so that the lives of a considerable proportion of sudden deaths can be saved; from retrograde to defibrillation, the probability of survival of the patient is reduced by approximately 7% -10% for each 1min delay.
