Heart Blocks ECG 9
- Normal sinus rhythm
- 3rd degree AV block (complete heart block)
- Osborne waves consistent with hypothermia
- Non-specific ST-T wave abnormalities
The ECG findings of hypothermia include a the classic Osborne wave characterized by a notch in the downward portion of the R wave in the QRS comples as seen below:
Some other ECG findings in hypothermia include low voltage, bradycardia (can be junctional, atrial fibrillation or higher grade AV blocks as in this ECG), artifact from shivering and non-specific ST-T wave abnormalities.
