Asystole

Asystole, also known as flatline, is a state of no electrical activity from the heart and therefore no blood flow. It results in cardiac arrest. Asystole is found initially in about 28% of people in cardiac arrest. Survival rates in a cardiac arrest patient with asystole are much lower than a patient with a rhythm amenable to defibrillation; asystole is itself not a "shockable" rhythm. Out-of-hospital survival rates (even with emergency intervention) are less than 2 percent.
