Time- and frequency-domain HRV measures were calculated from 60 min of ECG data obtained at three time points: 24 h (hypothermia), 48 h (hypothermia) and 96 h (normothermia).

The ECG findings of hypothermia include: An "Osborne wave" characterized by a notch in the downward portion of the R wave in the QRS complex. Low voltage.

In this ancillary study of a larger RCT, we found a high incidence of ECG changes and arrhythmias in pediatric patients with severe TBI. ... Thus, deep hypothermia is arrhythmogenic, ...

Her ECG is below: This ECG has many findings consistent with hypothermia. The classic finding is the “Osborne wave,” otherwise known as a “J wave.” ...

Hypothermia occurs when a person’s core body temperature drops below 95˚F. ... (ECG) to assess heart function. They may also use imaging tests, such as X-rays, ...

4 However, mortality in hypothermia appears to be related to the seriousness of the underlying pathology rather than the amplitude of the J-wave. Other ECG manifestations of hypothermia include ...

What Is the Diagnosis of This ECG? Kyuhyun Wang, MD. Disclosures. May 13, 2008. ... (Osborne) wave (↓). This is diagnostic of hypothermia, which is what this patient presented with. 1 2.

As such, hypothermia obscures normal premonitory ECG changes commonly associated with hyperkalemia. 1,4 There may also be elevation of the J point (if the ST segment is unaltered), producing a ...

Severe QTc prolongation under mild hypothermia treatment and incidence of arrhythmias after cardiac arrest — a prospective study in 34 survivors with continuous Holter ECG. Resuscitation 2011 ; 82 : ...
