Hypothermia results in the development of several characteristic electrocardiographic changes. As the core body temperature decreases, several changes in cardiac rhythm occur. Prolongation of the PR, QRS, and QT intervals are also seen. Muscle tremor artifact may be present, even in the absence of clinical shivering. A characteristic secondary deflection on the terminal portion of the QRS complex (Osborn wave) is usually found. All of these features are reversible with rewarming.
体温过低会导致出现几种典型的心电图变化。随着核心体温下降，会出现几种心律变化。还会观察到PR、QRS和QT间期延长。即使没有临床寒战，也可能出现肌肉震颤伪差。通常会在QRS波群终末部分发现一种特征性的继发性偏移（奥斯本波）。所有这些特征在复温后均可逆转。
