Classification
True PEA
There are no cardiac contractions despite electrical activity.
Pseudo PEA
There are very weak cardiac contractions present that fail to generate a blood pressure compatible with systemic perfusion and life despite electrical activity.
Post Defibrillation PEA
Following defibrillation, there can be a period of electromechanical dissociation where electrocardiographic complexes do not generate a pulse. As a result of post defibrillation PEA, it is often useful to continue CPR for up to one minute following restoration of a perfusing rhythm.
