Why is asystole not shockable? PEA is treated much like asystole. It is not a shockable rhythm because the electrical system in the heart is actually working properly.

What is the best treatment for asystole?
What is the best treatment for asystole? The only two drugs recommended or acceptable by the American Heart Association (AHA) for adults in asystole are epinephrine and vasopressin. Atropine is no longer recommended for young children and infants since 2005, and for adults sinceeless electrical activity (PEA) and asystole.
Why can't you shock asystole?
In asystole (flat line), there is no longer any effective electrical activity of the heart. There is basically no disorganized electrical activity to try to reset with a shock. That is why it makes no sense to shock someone in asystole. On television, people in flatline are shocked into a stable sinus rhythm. That just doesn't happen in real life.
Do you shock asystole?
The Advanced Life Support guidelines do not recommend defibrillation in asystole. They consider shocks to confer no benefit, and go further claiming that they can cause cardiac damage; something not really founder in the evidence.
Why defibrillation is not recommended in asystole?
The Advanced Life Support guidelines do not recommend defibrillation in asystole. They consider shocks to confer no benefit, and go further claiming that they can cause cardiac damage; something not really founder in the evidence.
What happens if you defibrillate asystole?
If it is fine v-fib, you may terminate the rhythm; however, if the rhythm is asystole, defibrillation will be ineffective and you can follow the asystole protocol with confidence.
Is asystole not shockable?
Asystole is a non-shockable rhythm. Therefore, if asystole is noted on the cardiac monitor, no attempt at defibrillation should be made. High-quality CPR should be continued with minimal (less than five seconds) interruption. CPR should not be stopped to allow for endotracheal intubation.
Which rhythm is not shockable?
Non- shockable rhythms include asystole and pulseless electrical activity. Shockable rhythms include ventricular fibrillation and pulseless ventricular tachycardia. The ECG algorithm (at end of document) can help you determine the proper steps.
Can you do CPR on asystole?
Asystole is treated by cardiopulmonary resuscitation (CPR) combined with an intravenous vasopressor such as epinephrine (a.k.a. adrenaline).
Does an AED shock asystole?
Children or adults who develop cardiac arrest caused by a slowing of the heart rate (bradycardia) or cardiac standstill (asystole) cannot be treated with an AED. These rhythms do not respond to electric shocks, so the AED will not allow a shock to be activated and standard CPR measures should be performed.
Is asystole the same as flatline?
Asystole is when your heart's electrical system fails entirely, which causes your heart to stop pumping. It is also known as “flat-line” or “flat-lining” because of how your heart's electrical activity appears as a flat line on an electrocardiogram.
Can ICD shock asystole?
The wearable cardioverter defibrillator (WCD) can deliver shocks to terminate ventricular tachycardia and fibrillation, and also alarms for asystole and severe bradycardia events which can alert bystanders to help.
What is the difference between PEA and asystole?
Asystole is the flatline reading where all electrical activity within the heart ceases. PEA, on the other hand, may include randomized, fibrillation-like activity, but it does not rise to the level of actual fibrillation.
What is the difference between shockable and non-shockable rhythm?
Many of our students ask the question "What is the difference between a shockable and non-shockable heart rhythm?" A shockable versus nonshockable initial rhythm can be determined by a shock as opposed to a no-shock message from an automated external defibrillator (AED) or by a review of the electronic recording.
What are the 2 shockable rhythms?
The two shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) while the non–shockable rhythms include sinus rhythm (SR), supraventricular tachycardia (SVT), premature ventricualr contraction (PVC), atrial fibrilation (AF) and so on.
Why can you not shock PEA?
Why not shock a PEA Arrest? In a PEA arrest, similar to Asystole, the heart doesn't have the means to use the shock you're sending it because the primary cause has yet to be corrected. Shocking a heart in PEA arrest is like kicking a comatose patient in the abdomen (which we do not recommend).
