Clinically, the three classic characterizing features of Cardiac arrest are :

• Pulselessness
• Unresponsiveness and
• Abnormal breathing — either agonal or absent.

The estimated annual incidence of out-of-hospital Cardiac arrest ranges anywhere from 250,000 to 420,000 and is still one of most common causes of death in the United States. There is a multitude of underlying etiologies with ischemic heart disease being the most common.

Common Causes of Nontraumatic Cardiac Arrest

There are four main conduction rhythms of Cardiac arrest :

Shockable with a more favorable outcome:

• Ventricular fibrillation (VF)
• Pulseless ventricular tachycardia (pVT).

Nonshockable:

• Pulseless electrical activity (PEA)
• Asystole.
