ABSTRACT
Effects of hypothermia CVS • Decreased cardiac output below 32°C with bradycardia and reduced MAP. • Vasoconstriction below 32°C, increasing afterload and thus myocardial
work. • ECG changes including widening QRS complex and increased PR interval,
prolonged QT interval and J waves. Risk of ventricular fibrillation (VF) below 28°C.
