That electrical current is detectable with a diagnostic test called an electrocardiogram (ECG or EKG). With PEA, your heart does have a detectable electrical current, but your heart isn’t strong enough to pump blood to the body. PEA can take two different forms:

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).

Nov 3, 2020 · 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

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...

Apr 7, 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 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 …

Dec 4, 2024 · Pulse Electrical Activity (PEA) is a condition where the heart slows electrical activity on the ECG, but there is no effective mechanical contraction. It means there is no palpable pulse or blood flow.

Jan 29, 2024 · PEA arrests are common in a hospital setting. One study found that PEA is the first documented rhythm in 30-38% of cardiac arrest patients and survival rates for those patients are poor. A critical component of ACLS must include steps to identify PEA on an EKG and respond quickly with appropriate treatment to improve outcomes for these patients.

Ventricular fibrillation is the result of numerous re-entry circuits, causing rapid and chaotic ventricular depolarizations, rendering the left ventricle incapable of generating effective contractions. This results in circulatory collapse, loss of …

Feb 20, 2025 · Pulseless Electrical Activity (PEA) is a critical medical condition where the heart’s electrical system functions, but the heart muscle fails to contract effectively, leading to the absence of a palpable pulse.
