Pulseless Electrical Activity is also known as which term?

• A. Electromechanical Dissociation
• B. Electrical Mechanical Arrest
• C. Vasovagal Episode
• D. Cardiac Arrest With Rhythm

Answer: (A)

Pulseless electrical activity means you can see organized electrical activity on the monitor, but there is no palpable pulse or usable blood flow. The term that best describes this situation is electromechanical dissociation, because it highlights the mismatch between the heart’s electrical signals and its mechanical pumping. The heart’s electrical system may be firing, but the mechanical action fails to produce contraction strong enough to generate a pulse, so there’s no perfusion despite the rhythm on the monitor. This is considered a form of cardiac arrest requiring CPR and reversal of causes. The other terms aren’t standard descriptors for this phenomenon: an Electrical Mechanical Arrest isn’t the recognized term; a vasovagal episode is a fainting event with a different mechanism and usually not a pulseless electrical state; and Cardiac Arrest With Rhythm is not a conventional label for this situation.
