In order to prevent the occurrence of cardiac arrest, normal electrical rhythm is essential; however, the role of a healthy heart muscle can't be ignored because a normal heartbeat results from the effective coordination of heart muscle and electrical activity. More than one mechanism may be involved in any given case. No. Sodium bicarbonate 1meq per kilogram may be considered in this rhythm as well, although there is little evidence to support this practice. An Overview of Hepatitis A, B, C, D & E for Medical Providers, How EMS Online Education Can Transform Patient Outcomes. Pulseless electrical activity is a very disconcerting emergency medical scenario with a very high mortality unless its etiology can be quickly ascertained and corrected. Van Walraven C, Forster AJ, Stiell IG. Pulseless electrical activity (PEA) refers to cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. As a result, PEA is usually noticed when a person loses consciousness and stops breathing spontaneously. Jordan MR, Morrisonponce D. Asystole. Resuscitation in the hospital: relationship of year and rhythm to outcome. Pulseless electrical activity follows somewhat similar treatment protocol as that of asystole. The immediate life-threatening problem is that this electrical activity is not associated with adequate mechanical (pumping) action, due for example to diffuse myocardial injury, pericardial tamponade, or severe loss of intravascular volume. A mnemonic to remember the different causes of pulseless electrical activity is: A useful way to remember the mnemonic is recalling Triple H, one of the biggest WWE stars, and his "mad cat". In this case, patient's airways must be maintained and protected. American Heart Association; 2011. Its routine use is not recommended for patients in this context, except in special situations (e.g. Toxins. Under normal circumstances, electrical activation of muscle cells precedes mechanical contraction of the heart (known as electromechanical coupling). All of these drugs should be administered along with appropriate CPR techniques. Causes of electromechanical dissociation (mnemonic). Identification of pseudo-electromechanical dissociation. Needle decompression may help treat the condition. Definition of PEA At present, there is no single unifying definition for PEA. Niemann JT, Stratton SJ, Cruz B, Lewis RJ. Hypothermia causes irresponsiveness to electrical or drug therapy. Thomas AJ, Newgard CD, Fu R, Zive DM, Daya MR. Pulseless electrical activity leads to a loss of cardiac output, and the blood supply to the brain is interrupted. [citation needed], The absence of a pulse confirms a clinical diagnosis of cardiac arrest, but PEA can only be distinguished from other causes of cardiac arrest with a device capable of electrocardiography (ECG/EKG). It is characterized by the accumulation of fluid in the sac that encloses the heart, pericardium. Current time: 11/12/2020 11:04:14 pm (America/New_York) Pericardiocentesis may treat this condition. Pulseless electrical activity is a life-threatening condition and must be treated as such irrespective of the causes. One of the significant finding of cardiac arrest is pulseless electrical activity(PEA).

Testori C, Sterz F, Behringer W, Haugk M, Uray T, Zeiner A, et al.Mild therapeutic hypothermia is associated with favourable outcome in patients after cardiac arrest with non-shockable rhythms. {"url":"/signup-modal-props.json?lang=us\u0026email="}. Despite a dramatic decrease in the age-adjusted risk of SCA, the cumulative number of fatal SCAs in the United States remains large. All rights reserved. The mainstay of drug therapy for PEA is epinephrine (adrenaline) 1 mg every 3–5 minutes. The medication epinephrine may be administered. It is characterized by entrapment of air in the pleural space that leads to buildup of tension, thereby, causing the shift of intrathoracic structure, which is followed by cardiovascular collapse and death. Pulseless electrical activity is found initially in about 55% of people in cardiac arrest.[1]. Estimates range from <170 000 to >450 000 fatal SCAs per year; a figure in the range of 300 000 to 370 000 per year is likely the best current estimate.1 SCA appears to account for ≈50% of all cardiovascular deaths,2 and it is estimated that 50% of the SCAs are the first clinical expression of previously undiagno… (2015). These are (1) impairment of cardiac filling, (2) impaired pumping effectiveness of the heart, (3) circulatory obstruction and (4) pathological vasodilation causing loss of vascular resistance and excess capacitance. Manual chest compression vs use of an automated chest compression device during resuscitation following out-of-hospital cardiac arrest: a randomized trial. Cardiac arrestwith initial arrest rhythmof pulseless electrical activity: do rhythm characteristics correlate with outcome? Now let's look at the symptoms you may have with pulseless electrical activity. [2] Epinephrine too has a limited evidence base, and it is recommended on the basis of its mechanism of action. ECG findings of toxicity include prolong QT interval. Pulseless electrical activity (PEA) occurs when a major cardiovascular, respiratory, or metabolic derangement results in the inability of cardiac muscle to generate sufficient force in response … [2], Cardiac resuscitation guidelines (ACLS/BCLS) advise that cardiopulmonary resuscitation should be initiated promptly to maintain cardiac output until the PEA can be corrected. Hyperkalemia causes widened QRS-wave and an elevated T-wave on an EKG. Pulseless electrical activity (PEA) refers to cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Engdahl J, Bang A, Lindqvist J, Herlitz J. Suitable antidote may be given to deal with the toxicity. [2] Epinephrine too has a limited evidence base, and it is recommended on the basis of its mechanism of action. Pulseless electrical activity is found initially in about 55% of people in cardiac arrest.[1]. As a result, PEA is usually noticed when a person loses consciousness and stops breathing spontaneously. [2] There is no evidence that external cardiac compression can increase cardiac output in any of the many scenarios of PEA, such as hemorrhage, in which impairment of cardiac filling is the underlying mechanism producing loss of a detectable pulse. They are hypoxia, hypovolemia, hypothermia, hyper/hypokalemia, hydrogen ion (acidosis), tension pneumothorax, tamponade (cardiac), toxins, and thrombosis (cardiac/pulmonary). A composite model of survival from out of hospital cardiac arrest using the Cardiac Arrest Registry to Enhance Survival (CARES). Approximately 300,000 out-of-hospital cardiac arrests (OHCA) occur annually in the United States, with a survival of 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, 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 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, 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, Various causes of PEA 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. [2], Cardiac resuscitation guidelines (ACLS/BCLS) advise that cardiopulmonary resuscitation should be initiated promptly to maintain cardiac output until the PEA can be corrected. It can be treated by surgical intervention and fibrinolytic therapy. [1], Pulseless electrical activity leads to a loss of cardiac output, and the blood supply to the brain is interrupted. They are also the most easily reversible and should be at the top of any differential diagnosis. [2] While PEA is classified as a form of cardiac arrest, significant cardiac output may still be present which may be determined and best visualized by bedside ultrasound. 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 resuscitation12.
