摘要

无脉电活动（PEA）表现为无脉搏的心电活动，通常预后较差。伪pea模仿真pea，但有残余的心脏运动可检测超声。这项初步研究表明，胸经胸阻抗（TTI），一种基于除颤器的测量方法，可能有助于区分伪pea和真pea。在回顾的10例病例中，TTI仅在伪pea中显示波形波动，这表明有可能改进识别和有针对性的复苏策略。

Transthoracic impedance waveform to distinguish pseudo-PEA from true-PEA

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.

期刊介绍： Resuscitation is a monthly international and interdisciplinary medical journal. The papers published deal with the aetiology, pathophysiology and prevention of cardiac arrest, resuscitation training, clinical resuscitation, and experimental resuscitation research, although papers relating to animal studies will be published only if they are of exceptional interest and related directly to clinical cardiopulmonary resuscitation. Papers relating to trauma are published occasionally but the majority of these concern traumatic cardiac arrest.
