Epidemiology of Ventricular Tachycardia/Ventricular Fibrillation and Sudden Cardiac Death: Epidemiologie de la Mort Subite

Despite the difficulties correlating pathological data with acute clinical events in the field of sudden cardiac death, information useful to both the clinician and the epidemiologist has developed. Sudden cardiac death may be defined broadly. These definitions have varied, but it is now generally recognized that sudden cardiac death should reflect a time span of less than one hour. The epidemiology of sudden cardiac death incorporates many factors, including age, heredity, gender, and race. Coronary risk factors and the history of prior coronary heart disease constitute additional points of importance. Finally, clinical characteristics of the cardiac arrest patient are variable. Improving outcome in prehospital cardiac arrest victims involves a multifactorial approach involving rescue personnel, resuscitation technology, and the participation of the public.
