Abstract
Pulseless electrical activity (PEA) presents with electrical cardiac activity without a pulse and often carries a poor prognosis. Pseudo-PEA mimics true-PEA but has residual cardiac motion detectable by ultrasound. This pilot study suggests thoracic transthoracic impedance (TTI), a defibrillator-based measure, may help differentiate pseudo-PEA from true-PEA. Among 10 reviewed cases, TTI showed waveform fluctuations only in pseudo-PEA, indicating potential for improved identification and targeted resuscitation strategies.
