摘要

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.
