In many patients with bradycardic circulatory arrest (PEA), percussion pacing can replace chest compressions until pharmacological or electrical intervention shows its effect.
What rhythms can you pace?
For pacing readiness (i.e. standby mode) in the setting of acute myocardial infarction (AMI) with the following:
- Symptomatic sinus bradycardia.
- Mobitz type II second-degree AV block.
- Third-degree AV block.
- New left, right or alternating bundle branch block or bifascicular block.
How do you treat PEA in ACLS?
When treating PEA, epinephrine can be given as soon as possible but its administration should not delay the initiation or continuation of CPR. High-quality CPR should be administered while giving epinephrine, and after the initial dose, epinephrine is given every 3-5 minutes.
What happens if you shock PEA?
In PEA, there is electrical activity but insufficient cardiac output to generate a pulse and supply blood to the organs, whether the heart itself is failing to contract or otherwise.

Is PEA a shockable rhythm?
Rhythms that are not amenable to shock include pulseless electrical activity (PEA) and asystole. In these cases, identifying primary causation, performing good CPR, and administering epinephrine are the only tools you have to resuscitate the patient.
Can you pace P wave asystole?
Pacing is a well recognised treatment in asystolic arrest with residual p wave activity. This can be achieved by transvenous, transthoracic, or manual external (cardiac percussion) pacing techniques.
Can you pace asystole?
Pacing is relatively contraindicated in patients with asystolic cardiac arrest, especially if the resuscitation efforts were delayed for more than 20 minutes, because of the poor resuscitation outcome in these patients.
What to do if someone is in PEA?
Regardless of the cause of PEA, the first step in treating this condition is always to begin chest compressions based on the advanced cardiac life support protocol. Epinephrine should also be administered every three to five minutes while the cause of the PEA is identified.
Why do you not shock PEA?
Pseudo-PEA is a form of severe shock in which diminished coronary perfusion leads to decreased myocardial function, thus further propagating hypotension. The pathologic insult causing the pseudo-PEA impedes the cardiovascular system’s ability to provide circulation throughout the body.
What is the difference between pulseless VT and PEA?
Pulseless electrical activity (PEA) and asystole are related cardiac rhythms in that they are both life-threatening and unshockable cardiac rhythms.
Rules for PEA and Asystole.
| PEA Regularity | Any rhythm including a flat line (asystole). |
|---|---|
| Rate | Any rate or no rate. |
| P Wave | Possible P wave or none detectable. |
How long can you survive PEA?
Survival and neurological recovery of PEA patients.
PEA patients survival to ROSC, 30-days and 1-year survival and neurological state described with CPC classification one year after resuscitation.
Can a flatline heart be restarted?
New research finds that it’s fairly common for the heart to restart — usually just for a beat or two — after a person initially flatlines. No one in the study, which took place in intensive care units (ICUs) in three countries, survived or even regained consciousness.
Is PEA the same as 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 are the 5 lethal rhythms?
You will learn about Premature Ventricular Contractions, Ventricular Tachycardia, Ventricular Fibrillation, Pulseless Electrical Activity, Agonal Rhythms, and Asystole. You will learn how to detect the warning signs of these rhythms, how to quickly interpret the rhythm, and to prioritize your nursing interventions.
Is PEA The first monitored rhythm?
The first monitored rhythm is VF/VT in approximately 25% of cardiac arrests, both in- or out-of-hospital. VF/VT will also occur at some stage during resuscitation in about 25% of cardiac arrests with an initial documented rhythm of asystole or PEA.
Can you pace a mi?
1. In patients presenting with an acute MI (myocardial infarction), temporary pacing is indicated for medically refractory symptomatic or hemodynamically significant bradycardia related to SND (sinus node dysfunction) or atrioventricular block.
Can you pace a heart block?
Transcutaneous pacing is the treatment of choice for any symptomatic patient. All patients who have third-degree atrioventricular (AV) block (complete heart block) associated with repeated pauses, an inadequate escape rhythm, or a block below the AV node (AVN) should be stabilized with temporary pacing.
Can you pace Vtach?
It has the capability of delivering an electric shock to the heart when it determines the heart rate is too fast. It also is capable of pacing or stimulating the heart when it is going too slow.
Can you touch a patient while pacing?
It is safe to touch patients (e.g. to perform CPR) during pacing.
Can you defibrillate bradycardia?
An implantable cardiac defibrillator is a device that monitors your heart rate and delivers a strong electrical shock to restore the heartbeat to normal in the event of tachycardia. Many defibrillators can also function as pacemakers, delivering a weaker shock to correct bradycardia as well.
Does no pulse mean no heartbeat?
A weak pulse means you have difficulty feeling a person’s pulse (heartbeat). An absent pulse means you cannot detect a pulse at all.
