PEA can be a precursor to sudden cardiac death, so its symptoms. No unique patterns were associated with the underlying causes or survival.Īetiology Cardiac arrest Causes Defibrillator Pulseless electrical activity Resuscitation.Ĭopyright © 2016 The Author(s). Pulseless electrical activity (PEA) is an especially serious heart arrhythmia related to weak or undetectable electrical activity. None of the patients with 'normal' PEA survived.Ībnormal ECG patterns were frequent at the early stage of in-hospital PEA. Abnormal ECG patterns were seen in all survivors. Further 7 episodes with a corresponding defibrillator file, but without a reliable cause, were included in analysis of survival. Your task for this case is to assess and manage a patient in cardiac arrest who has pulseless electrical activity (PEA). No unique cause-specific ECG pattern could be identified. Ninety percent (46/51) had widened QRS complexes, 63% (32/51) were defined as 'wide-slow' due to QRS-widened bradycardia, and only 6% (3/51) episodes were categorized as normal. Pulseless electrical activity (PEA) is characterized by the disassociation of the mechanical and electrical activity of the heart and appears as the initial. The defibrillator was attached after a median of one minute (75th percentile 3min) after the onset of arrest. QRS width and HR were considered to be normal below 120ms and within 60-100 cardiac cycles per minute, respectively.įifty-one episodes fulfilled the inclusion criteria. QRS width, QT interval, Bazett's corrected QT interval, presence of P waves and heart rate (HR) was determined. Prospectively observed episodes of IHCA presenting as PEA between January 2009 and august 2013, with a reliable cause of arrest and corresponding defibrillator ECG recordings, were analysed. The aim of this study was to investigate possible associations between early ECG patterns in PEA and the underlying causes and survival of in-hospital cardiac arrest (IHCA). A patients presenting rhythm is pulseless electrical activity (PEA). Pulseless electrical activity (PEA) is an increasingly common presentation in cardiac arrest. 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 acido.

PEA, formerly known as electromechanical dissociation, occurs in patients who have organized cardiac electrical activity without a palpable pulse. 5 Department of Circulation and Medical Imaging, Norwegian University of Science and Technology, Trondheim, Norway Department of Anaesthesia and Intensive Care Medicine, St.Olav University Hospital, Trondheim, Norway. 4 Department of Circulation and Medical Imaging, Norwegian University of Science and Technology, Trondheim, Norway Department of Cardiology, St.
