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.

Pulseless electrical activity (PEA) is defined as the presence of cardiac electrical activity with organized or partially organized cardiac rhythms without a palpable pulse. Pulseless electrical activity is formerly known as electromechanical dissociation (EMD).

Jun 15, 2023 · Pulseless electrical activity (PEA) is an especially serious heart arrhythmia related to weak or undetectable electrical activity. PEA can be a precursor to sudden cardiac death, so its...

Nov 3, 2020 · PSEUDO-PEA. Pseudo-PEA is essentially a severe shock state and is distinct from true electro-mechanical dissociation. Pseudo-PEA can be detected in the absence of a palpable pulse by: arterial line placement during cardiac arrest (identified by the presence of a blood pressure) high ETCO2 readings in intubated patients

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 …

For example, in cardiac arrest due to pulmonary embolism the initial rhythm is typically PEA, which is explained by the fact that the embolus prevents blood from passing from the lungs to the left ventricle, which therefore contracts without pre-load (the ventricle is empty or nearly empty).

This chapter will focus on ventricular fibrillation and pulseless electrical activity (PEA). These are highly lethal arrhythmias that lead to death if cardiopulmonary resuscitation is not started immediately.

PEA is defined as any organized rhythm without a palpable pulse and is the most common rhythm present after defibrillation. Learn all about PEA.

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 acido...

Pulseless Electrical Activity (PEA) looks like an organized rhythm, but the patient will have NO pulse and be unresponsive. Therefore, the rhythm doesn’t match your patient. The organized presentation of this rhythm can vary in that you may see something on the ECG that looks like normal sinus rhythm, sinus bradycardia, sinus tachycardia etc.
