What the Heck is Pseudo-PEA?

Pulseless electrical activity (PEA) is an organized electrical activity without a palpable pulse. 1/3 of cardiac arrest cases will be pulseless electrical activity and the overall prognosis of these patients is worse than patients who have shockable rhythms (ventricular fibrillation or pulseless ventricular tachycardia).

It can be a challenge to decide when to terminate or continue resuscitation efforts in PEA arrest. Palpating pulses is difficult in the setting of a code situation, neither sensitive nor specific based on current literature. The use of POCUS could help split PEA patients into Pseudo-PEA (cardiac activity on US = profound shock) vs True-PEA (no cardiac activity on…

 What the Heck is Pseudo-PEA?

The use of POCUS could help split PEA patients into Pseudo-PEA (cardiac activity on US = profound shock) vs True-PEA (no cardiac activity on US) in determining the potential for ROSC.

5 tips for managing the PEA cardiac arrest patient

Since the differential diagnosis for PEA is wide and ACLS offers little guidance, try these tips to improve the chances of patient survival.

Life in the Fastlane

In reality, pulseless electrical activity encompasses a very heterogeneous variety of severe circulatory shock states ranging in severity from pseudo-cardiac arrest to true electro-mechanical dissociation with cardiac standstill

StatPearls

Pulseless electrical activity does not necessarily mean the lack of mechanical activity. There can be ventricular contractions and detectable pressures in the aorta, which are also known as pseudo-PEA. True pulseless electrical activity is a state in which cardiac contractions are lacking in the presence of coordinated electrical impulses.
