Accidental hypothermia impacts the cardiovascular system, complicating patient management and prognosis. While previous studies have reported an association between hypothermia and ECG patterns, these findings are largely based on case reports or small-scale observational studies with limited sample sizes, underscoring the need for a more comprehensive analysis. ⋯ AF, PR prolongation, QT prolongation, and Osborn wave were observed to some extent even in mild hypothermia, and the frequency of these ECG patterns increased with severity increasing.
