A person can become asystolic due to a number of reasons including damage to the heart, disease, loss of blood, drug overdose, spike in potassium levels, oxygen deprivation, uncommon heartbeat, cardiac arrest, etc. PEA can cause conditions such as hypovolemia and hypoxia, two common results of PEA. Higher doses of epinephrine have not shown to improve survival or neurologic outcomes in most patients. Estera Veer | 18th April 2020. Lacking a pulse is different from asystole, despite the parallels between the connotation of both terms. However, arrhythmia is much more complex. In: StatPearls [Internet]. Out-of-hospital cardiac arrest patients in asystole should also be considered for the cessation of efforts according to local protocol 9). In cases of PEA or asystole, atropine is no longer recommended. Check pulse and rhythm every 2 minutes, as follows: If nonshockable, see Nonshockable Rhythm (below). The current algorithm has eliminated the “look, listen, and feel” step to check for breathing in an unresponsive patient. Hypothermia, resulting from prolonged exposure to the elements, particularly the extreme cold. Push hard and fast, at least one-third anteroposterior (AP) chest diameter and 100-120 compressions per minute. The risk of pulseless electrical activity increases over the age of 70, especially in the female population. Obtain intravenous (IV)/intraosseous (IO) access. They include the Hs and Ts discussed below and their causes. High-quality CPR is the mainstay of treatment and the most important predictor of favorable outcome. Pulseless electrical activity and asystole are deadly algorithms if left untreated.

If shockable, see Shockable Rhythm (above) and administer amiodarone or lidocaine after second defibrillation attempt. The definition of asystole is a type of a cardiac arrest rhythm that has no distinct electrical activity seen on the ECG machine. Asystole is the more life-threatening arrhythmia.

Hypoglycemia, occurring from a rapid decline in blood serum glucose levels. Thrombosis (both pulmonary and coronary). Pulseless Electrical Activity. 1. Two cardiac rhythms that are similar because they are both unshockable and life-threatening are pulseless electrical activity (PEA) and asystole However, any cause of cardiac arrest can eventually result in asystole if not promptly treated. However all patients with PEA will have no detectable cardiac output. The image below shows some differences among the waveforms: When electrical activity moves beyond the level of fibrillation and appears to not represent any particular rhythm, it may be described as PEA. The cause of PEA (pulseless electrical activity) is classified into primary/cardiac and secondary/noncardiac causes. If the patient is not breathing or only has agonal respirations, the rescuer should check for a carotid pulse for the unresponsive adult or the brachial pulse in the unresponsive infant for no more than 10 seconds. Asystole is commonly referred to as “flatline”. 10 The initial rhythm may be ventricular fibrillation (VF), pulseless ventricular tachycardia (VT), asystole, or pulseless electrical activity (PEA). Near pulseless electrical activity or a very low-output state may also be managed with the circulatory assistance (e.g., intra-aortic balloon pump, extracorporeal membrane oxygenation, cardiopulmonary bypass, and ventricular assist device). Causes of asystole in cardiac arrest are wide and varied. Combining medications is not recommended and may cause harm. Cardiac Arrest can be any number of pulseless heart rhythm, Asystole included. Chan PS, Jain R, Nallmothu BK, Berg RA, Sasson C. Rapid Response Teams: A Systematic Review and Meta-analysis. As a medication it belongs to the sympathomimetic drugs class and is used to treat a number of conditions, including anaphylaxis, cardiac arrest, and superficial bleeding. Respiratory failure leading to hypoxia is one of the most common causes of pulseless electrical activity, responsible for about half of the PEA cases. Continue CPR for 2 minutes.

Health professionals should carefully monitor any child in distress for signs of decompensation and the onset of bradycardia. Asystole is a flat-line ECG (Figure 27). While preliminary research showed that high doses of epinephrine can possibly produce better results for resuscitation, research conducted after the publication of the 2010 guidelines haven’t proven any better results from administering epinephrine over the standard dose of 1 mg. Save my name, email, and website in this browser for the next time I comment. It is the absence of myocardial electrical activity and therefore produces no cardiac output.The patient is pulseless and non-responsive.Rapid initiation of CPR and ALS measures is vital. She graduated from Vilnius University with a degree in Marketing and Global Business and studied in Slovakia, Portugal as an exchange student, and is currently residing in Vilnius, Lithuania, Your email address will not be published.
This includes a lack of P-waves, QRS complexes, and T-waves. Causes of secondary pulseless electrical activity include the famous “Hs and Ts.” These are as follows: Pulseless electrical activity occurs when an insult involving cardiovascular system, gastrointestinal tract or the respiratory system results in the inability of the cardiac muscle to generate adequate force in response to electrical depolarization. Hydrogen ion buildup, also known as acidosis, which may result from problems of the endocrine system or even non-medically supervised dietary changes.

Patches must always have secure contact with the patient, cables must be connected, gain appropriately set, and the device turned on. In these cases, it still carries the PEA diagnosis, but the cause of arrest is directly interfering with either the EKG’s accuracy or the cause of arrest, such as trauma, is beginning to inhibit the ability of the body to maintain a regular rhythm.

An impalpable pulse should not always be taken as a PEA (pulseless electrical activity) because it may be due to severe peripheral vascular abnormality. This ensures adequate perfusion of tissues and promotes ROSC. Asystole refers to an abnormal cardiac rhythm as indicated by an electrocardiogram (ECG) machine. If the blood volume is insufficient, due to hemorrhage, any contraction will still not carry enough blood flow to support reoxygenation and provide nutrients through the coronary vessels. Arch. Consider the reason asystole is an unshockable rhythm. Heart rate: Ventricular rate of 100 bpm or above. Females are more likely to develop PEA (pulseless electrical activity) as compared to the male population. Be certain that you are not dealing with user or equipment failure when reading asystole. The following are other mechanisms for pulseless electrical activity: Decreased cardiac contractility has been related to changes in intracellular calcium levels, which explains why patients with beta blockers or calcium channel blockers are more prone to developing pulseless electrical activity and may become unresponsive to therapy. There does exist another instance in which high-dose epinephrine may be acceptable in the course of treatment of cardiac arrest. Thrombosis of the coronary vessels, preventing the perfusion of blood into cardiac tissues. google_ad_client: "ca-pub-9759235379140764", Both types of asystole may also occur untreated ventricular fibrillation and before attempts to defibrillate. Have you ever been in a health facility where someone did not know how to determine between PEA and asystole, or have you ever considered a child’s care when his pulse drops below 60? Atropine, which does have some evidentiary support for its use, was found to offer no therapeutic benefit to patients.

A person can become asystolic due to a number of reasons including damage to the heart, disease, loss of blood, drug overdose, spike in potassium levels, oxygen deprivation, uncommon heartbeat, cardiac arrest, etc. PEA can cause conditions such as hypovolemia and hypoxia, two common results of PEA.
