In adults, cardiac arrests are often due to ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) in the presence of underlying coronary artery disease (CAD). Children with cardiac arrest rarely have CAD; commonly documented rhythms are bradycardia, asystole, or pulseless electrical activity (PEA) generally resulting from progressive tissue hypoxia and acidosis (due to respiratory failure, circulatory shock, or both). These researchers acquired insights about in-hospital cardiac …
