Pulseless electrical activity and asystole

What rhythm is a flat line?

Asystole (ay-sis-stuh-lee) is when there’s no electricity or movement in your heart. That means you don’t have a heartbeat. It’s also known as flatline. That’s because doctors check the rhythm of your heart with a machine called an electrocardiogram — also called an ECG or EKG.

Is asystole flatline a shockable rhythm?

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.
