[[Sudden cardiac death]] is a natural, rapid, unexpected death secondary to [[cardiac]] cause or mechanism. [[Sudden cardiac arrest]] is defined as the unexpected cessation of pumping blood into vital organs due to electrical disturbance in the pathway of [[SA node]], [[AV node]], [[Hiss Purkinje fibers]] or pumping failure due to conditions such as [[cardiogenic shock]], [[massive pulmonary thromboembolism]],[[fulminant myocarditis]], [[ruptured left ventricular free wall]]. Without any intervention for immediate restoration of the [[circulation]], biologic death or [[sudden cardiac death]] will happen minutes to weeks after cardiac arrest. [[Sudden cardiac death]] is responsible for 50% of cardiac death annually in the united state. In-hospital [[cardiac arrest]] happens in 290,000 adults annually in the united states. The most common cause of [[sudden cardiac death]] is [[coronary artery disease]] and [[atherosclerosis]] process. The presence of underlying disorders such as [[malignancy]] or [[liver disease]] at the time of cardiac arrest makes the condition worst.

Sudden cardiac death is a natural, rapid, unexpected death secondary to cardiac cause or mechanism. Sudden cardiac arrest is defined as the unexpected cessation of pumping blood into vital organs due to electrical disturbance in the pathway of SA node, AV node, Hiss Purkinje fibers or pumping failure due to conditions such as cardiogenic shock, massive pulmonary thromboembolism,fulminant myocarditis, ruptured left ventricular free wall. Without any intervention for immediate restoration of the circulation, biologic death or sudden cardiac death will happen minutes to weeks after cardiac arrest. Sudden cardiac death is responsible for 50% of cardiac death annually in the united state. In-hospital cardiac arrest happens in 290,000 adults annually in the united states. The most common cause of sudden cardiac death is coronary artery disease and atherosclerosis process. The presence of underlying disorders such as malignancy or liver disease at the time of cardiac arrest makes the condition worst. Patients with acute myocardial infarction and in-hospital cardiac arrest with shockable rhythm have a better prognosis. Post cardiopulmonary resuscitation state management should be focused on neurologic complications, hemodynamic stability, and respiratory support.
