Can hypothermia-induced changes in QRS and QT(c) intervals predict cardiac arrest?

Hypothermic cardiac arrest (HCA) is often caused by ventricular tachyarrhythmias in severe hypothermia. The QRS/QTc ratio may predict arrhythmia risk, but data are insufficient. Routine QRS/QTc measurements during transport and in-hospital care, along with consistent reporting, could improve understanding, management, and survival outcomes in severe accidental hypothermia cases.

Abstract

Hypothermic cardiac arrest (HCA) is often caused by ventricular tachyarrhythmias in severe hypothermia. The QRS/QTc ratio may predict arrhythmia risk, but data are insufficient. Routine QRS/QTc measurements during transport and in-hospital care, along with consistent reporting, could improve understanding, management, and survival outcomes in severe accidental hypothermia cases.
