Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests. [2]
3 lis 2020 · OVERVIEW. Pulseless electrical activity (PEA) occurs when organised or semi-organised electrical activity of the heart persists but the product of systemic vascular resistance and the increase in systemic arterial flow generated by the ejection of the left ventricular stroke volume is not sufficient to produce a clinically detectable pulse.
7 kwi 2023 · Pulseless electrical activity (PEA), also known as electromechanical dissociation, is a clinical condition characterized by unresponsiveness and impalpable pulse in the presence of sufficient electrical discharge.
Pulseless electrical activity (PEA) is a condition where you don't have a pulse. Your heart stops, and you're in cardiac arrest. Without medical attention, your heart can't recover by itself.
14 cze 2021 · Pulseless electrical activity (PEA) is a common initial rhythm in cardiac arrest. A substantial number of PEA arrests are caused by coronary ischemia in the setting of acute coronary occlusion, but the underlying mechanism is not well understood.
15 sty 2020 · Pulseless electrical activity (PEA) accounts for up to 25% of sudden cardiac arrest; 1 therefore the ability to recognize and care for this condition is an essential skill of emergency medicine physicians.
15 lut 2022 · PEA is often seen during resuscitation, either as the presenting clinical state in cardiac arrest or as a secondary rhythm following transient return of spontaneous circulation (ROSC), ventricular fibrillation/tachycardia (VF/VT), or asystole (ASY).
