Overview
PEA can be classified as cardiac and non cardiac depending on the initial underlying etiology. Cardiac PEA can be further classified as primary and secondary to a preceding ventricular tachycardia or ventricular fibrillation.[1] Pulseless electrical activity can be classified either by the intensity of cardiac contractions or their electrical manifestations (true or psuedo PEA), and by electrocardiographic features. These three can overlap and ultimately be classified by the electrical manifestations, and having different electrocrdiographic patterns in each of them. </ref> Dragsund, I, K Gundersen, M Risdal, J Kramer-Johansen, D Edelson, F Sterz, and T Eftestøl.
