Increasing heart rate and decreasing QRS complex width during ALS was significantly more prevalent in patients who obtained return of spontaneous circulation compared to patients who were declared dead.Ĭhanges in ECG characteristics during ALS in cardiac arrest presenting as PEA are related to prognosis. A total of 2187 combined observations of QRS complex rate (heart rate) and QRS complex width for the duration of ALS were determined from defibrillator recordings from 74 episodes of cardiac arrest. Olav Hospital (Trondheim, Norway) over a three-year period were included. Patients with in-hospital cardiac arrest with initial PEA at St. Pulseless rhtyhms that are excluded by definition include VF, VT, and asystole. The aim of this study was to examine the development of ECG characteristics during advanced life support (ALS) and cardiopulmonary resuscitation (CPR) in cardiac arrest with initial PEA, and to assess any association with survival. Any organized rhythm wihout a pulse is defined as PEA. What you see on the monitor: Asystole appears as a nearly flat line (except for those changes caused by chest compressions).
Rapid initiation of CPR and ALS measures is vital. The patient is pulseless and non-responsive. When done close the diagram.Pulseless electrical activity (PEA) is a frequent initial rhythm in cardiac arrest, and ECG characteristics have been linked to prognosis. It is the absence of myocardial electrical activity and therefore produces no cardiac output. View the cardiac arrest algorithm diagram. The pulse check should be performed simultaneously with the rhythm check when treating PEA since by definition PEA is an organized rhythm and could have a pulse that generates blood perfusion. Limit the rhythm/pulse check to less than 10 seconds to minimize interruptions in CPR. High-quality CPR should be administered while giving epinephrine, and after the initial dose, epinephrine is given every 3-5 minutes.įor PEA a rhythm and pulse check should be performed after 5 cycles of CPR. When treating PEA, epinephrine can be given as soon as possible but its administration should not delay the initiation or continuation of CPR.
Vasoconstriction is important during CPR because it will help increase blood flow to the brain and heart.
The vasopressor that is used for the treatment within the right branch of the Cardiac Arrest Algorithm is epinephrine.Įpinephrine is primarily used for its vasoconstrictive effects. Medications used in PEA VasopressorsĪ vasopressor is a medication that produces vasoconstriction and a rise in blood pressure. These factors are primarily associated with PEA, but having a working knowledge. Identification and correction of the cause of PEA. The 'Hs and Ts' is a mnemonic device which will help you to recall the factors that contribute to pulseless arrest, include Pulseless Electrical Activity (PEA), Asystole (flatline), Ventricular Fibrillation (VFib or VF), and Ventricular Tachycardia (VTach or VT). What Is PEA (Pulseless Electrical Activity) And Why Is It Bad For students who are in ECG/EKG training, PEA (pulseless electrical activity) is a physical condition that causes no palpable pulse with unresponsiveness, while cardiac electrical activity is still organized and present, also known as electromechanical dissociation (EMD). Positive outcome of an attempted resuscitation depends primarily on two actions: 1. Pulseless electrical activity (PEA) is an increasingly common presentation in cardiac arrest.
