Pulseless Electric Activity

Factors associated with pulseless electric activity versus ventricular fibrillation: the Oregon sudden unexpected death study.

BACKGROUND Corresponding with a continuing decline in the prevalence of sudden cardiac arrest cases presenting with ventricular fibrillation (VF), there has been a significant rise in the prevalence of pulseless electrical activity (PEA). Given significantly lower survival from PEA versus VF, we comprehensively investigated PEA correlates by incorporating first-responder data with lifetime clin...

Atropine, halothane, and pulseless electrical activity.

C ardiovascular depression from halothane overdose is a well-described cause of cardiac arrest in children undergoing anesthesia. In Salem et al’s (1) report of cardiac arrests in infants and children, seven of 73 were related to overdose of halothane. In Keenan and Boyan’s (2) landmark article on cardiac arrest due to anesthesia, five of six pediatric arrests were due to halothane excess, with...

Application of ultrasound in pulseless electrical activity (PEA) cardiac arrest

Outcome of out-of-hospital postcountershock asystole and pulseless electrical activity versus primary asystole and pulseless electrical activity.

OBJECTIVE In the prehospital setting, countershock terminates ventricular fibrillation (VF) in about 80% of cases. However, countershock is most commonly followed by asystole or pulseless electrical activity (PEA). The consequences of such a countershock outcome have not been well studied. The purpose of this investigation was to compare the outcome of prehospital VF victims shocked into asysto...

Pre-pulseless and Pulseless Takayasus' Arteritis

The Confused Terminology and Changing Concept of Takayasu's Arteritis In 1908 the Japanese opihthalmologist, Takayasu, reported an unusual wreath-like vascular anastomosis surrounding the optic discs of a young female patient who was nearly iblind, biut who showed 'no general physical changes'. He was unalble to explain this abnormality. Laiter a colleague, Onishi, referred to a similar case wh...
