Is PEA and asystole shockable?
Both PEA and asystole remain non shockable rhythms. With that in mind, treating the causes of arrest should lead to a period where the rhythm enters a shockable state.
Do you shock for pulseless Vtach?
Shockable Rhythm: Pulseless V-tach V-tach is a poorly perfusing rhythm and patients may present with or without a pulse. Most patients with this rhythm are pulseless and unconscious and defibrillation is necessary to reset the heart so that the primary pacemaker (usually the SA node) can take over.
What are the two most common causes pulseless electrical activity?
Hypovolemia and hypoxia are the two most common causes of PEA. They are also the most easily reversible and should be at the top of any differential diagnosis. If the individual has a return of spontaneous circulation (ROSC), proceed to post-cardiac arrest care.

Various causes of pulseless electrical activity include significant hypoxia, profound acidosis, severe hypovolemia, tension pneumothorax, electrolyte imbalance, drug overdose, sepsis, large myocardial infarction, massive pulmonary embolism, cardiac tamponade, hypoglycemia, hypothermia, and trauma.
What is the most common cause of PEA?
Hypoxia secondary to respiratory failure is probably the most common cause of PEA, with respiratory insufficiency accompanying 40-50% of PEA cases. Situations that cause sudden changes in preload, afterload, or contractility often result in PEA.
Will an AED shock pulseless electrical activity?
If the AED detects Ventricular Tachycardia (VT) or Ventricular Fibrillation (VF), then it will deliver a shock. If it discovers Asystoleor Pulseless Electrical Activity (PEA), the AED will alert the user and say, “No shock advised.”
How Common Is PEA Arrest?
PEA arrests are a surprisingly common occurrence in the hospital setting.

A shockable rhythm is one caused by abnormalities in the electrical conduction in the heart. These include:
What Happens If You 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.
What is a PEA arrest?
A PEA arrest is the first documented rhythm in as many as 38% of adults experiencing hospital cardiac arrest (IHCA).
Why is asystole unshockable?
Because of the nature of the disruption, the heart experiencing Asystole no longer has the means to move an electrical current generated by defibrillation through the heart. It is therefore unshockable.
What happens when you have a PEA arrest?
However, in the case of a PEA arrest, the vascular system has collapsed. Without the vascular system, that blood can’t get to other vital organs, so the brain and lungs stop. In reality, the vascular system should also be considered a vital organ. Now death begins. The heart continues to pump until it no longer has the oxygen it needs for cardiac functions. Loss of effective pulse happens next. This loss of pulse is the beginning of PEA arrest.
How to treat PEA?
PEA is not a shockable rhythm and treatment for PEA involves high quality CPR, airway management, IV or IO therapy, and appropriate medication therapy . The primary medication is going to be 1mg epinephrine 1:10,000 every 3-5 minutes rapid IV or IO push. In order to correct PEA, the ultimate goal is to identify and treat the underlying cause of the cardiac arrest.
What is Pulseless Electrical Activity (PEA)?
Pulseless electrical activity, also commonly referred to as PEA, is a condition where the electrical activity of the heart isn’t accompanied by a palpable or effective pulse. Healthcare providers need to find the potential cause and correct it, which will hopefully restore the patient’s pulse.
What happens if you have a PEA?
A patient with PEA will be unconscious with no pulse or normal breathing. Pulseless electrical activity leads to a loss of cardiac output and discontinues blood supply to the brain. The skin may appear pallor due to a lack of oxygen in the blood.

Signs and Symptoms of Pulseless Electrical Activity (PEA) A patient with PEA will be unconscious with no pulse or normal breathing. Pulseless electrical activity leads to a loss of cardiac output and discontinues blood supply to the brain. The skin may appear pallor due to a lack of oxygen in the blood.
What Are ECG Characteristics of Pulseless Electrical Activity?
Pulseless electrical activity can present as any organized or partially organized rhythm on an electrocardiogram (ECG). Examples include sinus rhythm, atrial fibrillation, bundle branch blocks, or idioventricular rhythms (a rhythm where you would expect and pulse and there is none).
What is the difference between pseudo-PEA and true-PEA?
Pulseless electrical activity can be separated into pseudo-PEA or true-PEA. Pseudo-PEA occurs when the patient has no palpable pulse, yet identifiable pressures within the aorta and weak ventricular contractions are present. True-PEA occurs when electrical impulses are firing without cardiac contractions.
What is PEA in medical terms?
Pulseless electrical activity (PEA) is defined as the presence of cardiac electrical activity with organized or partially organized cardiac rhythms without a palpable pulse. Pulseless electrical activity is formerly known as electromechanical dissociation (EMD). During PEA, the heart is unable to move adequate blood volume to maintain systemic perfusion.
What is AMRI certification?
American Medical Resource Institute (AMRI) prepares you for successful completion of your BLS, ACLS, or pediatric advanced life support (PALS) certification (s) so that you may effectively respond to a life-threatening emergency and apply your knowledge and skills to improve potential patient outcomes. AMRI provides rigorous, innovative, and multidisciplinary opportunities to maximize your learning and offers a flexible and convenient learning environment. You can complete your coursework and exam according to your schedule, on any device.
What happens to the heart when it is pulseless?
Pulseless electrical activity occurs due to an event that takes place within the respiratory, cardiovascular, or gastrointestinal systems of the body which contributes to insufficient force generated by the heart following electrical depolarization . This insufficient force results in a weakened ability of the heart to contract, which can lead to a worsening cascade of pathophysiological changes such as hypoxia, acidosis, and decreased vagal tone. Further impairment of the contractility of the heart results, despite the presence of electrical activity within the heart, and mechanical activity of the heart becomes insufficient. The risk for clinical mortality is increased in patients experiencing pulseless electrical activity.
What happens if you register for AMRI?
Did you know that if you register for your certification course through AMRI that you will have access to an expanded library of case studies and practice tests that are otherwise unavailable to the public?
Is ventricular fibrillation a pulseless electrical activity?
Rhythms such as ventricular fibrillation and pulseless ventricular tachycardia are not associated with pulseless electrical activity (despite being pulseless) as they tend to respond to defibrillation. Asystole is considered a separate rhythm than pulseless electrical activity.
What Is Pulseless Electrical Activity?
Pulseless electrical activity occurs when a patient has cardiac electrical activity but no pulse. This means that no mechanical contracts are occurring, despite organized electrical activity in the heart. The pulseless electrical activity includes any type of cardiac arrest rhythm that cannot be categorized as asystole, ventricular fibrillation, or pulseless ventricular tachycardia. Pulseless electrical activity was previously referred to as “electromechanical dissociation.”
How to get ACLS certification?
To obtain the ACLS certification you need to remain compliant at work and be prepared to treat conditions like pulseless electrical activity, you need to complete an ACLS course at regular intervals. Three different course structures are available to healthcare professionals who need ACLS certification: in-person courses, hybrid courses and online courses.
Why does myocardial infarction cause pulseless electrical activity?
Pulseless electrical activity may occur because of any issue that inhibits the shortening of myocardial fibers, thus preventing mechanical contractions. Possible causes of pulseless electrical activity include ionic perturbations, metabolic acidosis, ischemia and hypoxia. Patients may experience PEA after a drug overdose, myocardial infarction, ...
What is ACLS in person?
In-person ACLS courses are completed entirely in a classroom setting. When you choose this type, of course, you will complete all of your coursework while surrounded by other students. You will also take your exam in-person. These programs are ideal for students who want face-to-face interactions with teachers and hands-on learning experiences. However, there are drawbacks to in-person courses as well. For example, when you enroll in an in-person course, you must attend scheduled sessions that could interfere with your other obligations.
How to choose ACLS course?
In order to choose the right ACLS course for your needs, it is important to consider your own needs and preferences. For example, if you are someone who benefits from face-to-face interactions, you may prefer to study in person. However, if you are someone who prefers to set your own schedule and would rather not deal with the constraints of an in-person program, you may benefit more from an online or hybrid course.
What is the treatment for a clot in the heart?
Treating cardiac thrombosis usually involves an intervention designed to resolve the clot, such as primary percutaneous coronary intervention or coronary angiography.
What is the treatment for hyperkalemia?
The treatment of hyperkalemia involves protecting the heart, shifting potassium into cells and taking steps to remove potassium from the body.
What is IV/IO access?
116. IV/IO access is a priority over advanced airway management unless bag-mask ventilation is ineffective or the arrest is caused by hypoxia. Defibrillation is not indicated for asystole and is not used in the asystole algorithm.)
How long should you interrupt CPR?
1 (ten seconds. AHA ACLS provider manual pg. 116. "Interrupt CPR for 10 seconds or less while you perform rhythm check." The longer the interruption of CPR the less likely that the resuscitation will be successful. )
Why is IV access important in AHA?
High quality CPR is first because it is the foundation for a successful resuscitation. IV access is next because IV access is needed for the administration of resuscitation medications that can help reverse cardiac arrest. Finally, advanced airway placement can help improve the patient's respiratory status during a resuscitation. )
When to use unsynchronized shocks?
Unsynchronized shocks are recommended for a patient who is pulseless, for a patient demonstrating clinical deterioration (in prearrest) when you think a delay in converting the rhythms will result in cardiac arrest, and when you are unsure whether monomorphic or polymorphic VT is present in the unstable patient.")
How long should you pause chest compressions?
Even a 5- to 10-second pause in chest compressions can reduce the chance that a shock will terminate VF.
What are the symptoms of tension pneumothorax?
3 (Major symptoms of PEA associated with tension pneumothorax include unequal breath sounds, difficulty with ventilation and neck vein distention. Most common seen during CPR will be difficulty with ventilation. This will also more commonly be associated with chest trauma.)
What is a tamponade?
Cardiac tamponade is a condition in which an accumulation of fluid within the pericardium creates excessive pressure, which then prevents the heart from filling normally with blood. This can critically decrease the amount of blood that is pumped from the heart, which can be lethal.
What causes pulseless electrical activity?
Various causes of pulseless electrical activity include significant hypoxia, profound acidosis, severe hypovolemia, tension pneumothorax, electrolyte imbalance, drug overdose, sepsis, large myocardial infarction, massive pulmonary embolism, cardiac tamponade, hypoglycemia, hypothermia, and trauma. 21 The 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care list the “ 5 Hs and 5 Ts ” that should be evaluated and treated when attempting to diagnose the cause (s) of PEA. They are hypoxia, hypovolemia, hypothermia, hyper/hypokalemia, hydrogen ion (acidosis), tension pneumothorax, tamponade (cardiac), toxins, and thrombosis (cardiac/pulmonary). Often, a standardized treatment algorithm is deployed that is the same for each patient in PEA regardless of the etiology, particularly in the prehospital setting, due to the time-critical nature of the disease and lack of a clear identifiable etiology during resuscitation 12. Characteristics of the PEA arrest rhythm may help with determining who would benefit from aggressive postcardiac care interventions such as therapeutic hypothermia. 2,8,18,9
How many out-of-hospital cardiac arrests occur annually in the United States?
Approximately 300,000 out-of-hospital cardiac arrests (OHCA) occur annually in the United States, with survival around 8%. 10 The initial rhythm may be ventricular fibrillation (VF), pulseless ventricular tachycardia (VT), asystole, or pulseless electrical activity (PEA). 16 Two-thirds of OHCA has an initial non-shockable rhythm of PEA or asystole with an increasing incidence compared with initial shockable rhythms (ventricular fibrillation and pulseless ventricular tachycardia). 1,19
How common is a PEA in hospital?
Several studies have shown the incidence of PEA in-hospital to be approximately 35% to 40% of arrest events. 20,15 For out-of-hospital cardiac arrest, the incidence of PEA is 22% to 30%. 5,6 PEA arrests are associated with a poor prognosis, with a survival to discharge rate between 2% and 5% for out-of-hospital cardiac arrest. 17,3 In addition, pulseless electrical activity after countershock is correlated with a worse prognosis than PEA presenting as the initial rhythm, with 0% to 2% of patients in post-countershock PEA surviving to discharge. 13 Furthermore, post-countershock PEA with a slow and wide complex rhythm is associated with a worsened prognosis compared to the rapid, narrow complex PEA. 11
What is PEA in cardiac arrest?
PEA, formerly known as electromechanical dissociation, occurs in patients who have organized cardiac electrical activity without a palpable pulse. 11 The absence of mechanical contractions is produced by factors that deplete myocyte high-energy phosphate stores and inhibit myocardial fiber shortening, including hypoxia, ischemia, metabolic acidosis, and ionic perturbations (particularly potassium and calcium changes). 14 All cardiac arrest rhythms—that is, pulseless rhythms—that fall outside the category of pulseless ventricular tachycardia, ventricular fibrillation, or asystole are considered pulseless electrical activity. 11
What is PEA treatment?
PEA is a disease process with multiple etiologies, and effective treatment likely includes reversing the cause of cardiac arrest. 7 Understanding the potential pulseless electrical activity causes and treatments will enable providers to give the best possible care in a situation that statistically does not have positive outcomes.
What is pseudo PEA?
Pseudo-PEA is a profound state of cardiogenic shock that is inadequate to maintain perfusion pressure (and thus a nondetectable pulse). 11 Pseudo-PEA has the presence of aortic pulse pressures with a perfusion pressure less than 60 mm Hg. 14 In pseudo-PEA, cardiac electrical activity is present with myocardial contractions that are not adequate to produce a palpable pulse. 11 Pseudo-PEA is a form of severe shock in which diminished coronary perfusion leads to decreased myocardial function, thus further propagating hypotension. 14 The pathologic insult causing the pseudo-PEA impedes the cardiovascular system’s ability to provide circulation throughout the body. 11 In the spectrum of PEA etiologies, pseudo-PEA is frequently caused by hypovolemia, tachydysrhythmias, decreased cardiac contractility, or obstructions to circulation, such as pulmonary embolism, tamponade, and tension pneumothorax. 4 Pseudo-PEA rhythms are often narrow QRS complex tachycardias. 11
What is true PEA?
True PEA represents a more severe pathophysiology in which there is a complete absence of mechanical contractions—a true uncoupling of cardiac mechanical activity from the cardiac rhythm. 11 Unlike the reduced aortic pressures of pseudo-PEA, true PEA is characterized by the absence of any aortic pulse pressures. 11 True PED is characterized by profoundly slow rhythms with wide QRS complexes. 11 The electrical component is characterized by an abnormal automaticity, usually seen at a slow ventricular rate with a wide QRS complex (QRS >0.12 seconds). 11 Etiologies frequently associated with true PEA include large myocardial infarction, multiorgan failure, profound metabolic imbalances such as hyperkalemia, drug overdoses, hypothermia, acidosis, and prolonged cardiac arrest. 11
