Summary
Severe hypothermia after water submersion caused significant ECG changes, including Osborn waves and prolonged durations. These abnormalities resolved with rewarming, highlighting hypothermia
Area of Science:
- Cardiology
- Environmental Medicine
- Emergency Medicine
Background:
- Hypothermia, a dangerous drop in body temperature, poses significant risks following cold-water immersion.
- Respiratory insufficiency is a common complication of severe hypothermia.
- Electrocardiogram (ECG) abnormalities are frequently observed in hypothermic patients.
Observation:
- A 32-year-old male presented with severe hypothermia and respiratory distress post-submersion.
- Initial ECG revealed characteristic Osborn waves (J waves) and prolonged QRS and QT intervals.
- The patient's condition necessitated immediate medical intervention and rewarming.
Findings:
- The presence of Osborn waves on ECG is a hallmark of hypothermia.
- Prolonged QRS and QT durations indicate impaired cardiac conduction and repolarization.
- Complete normalization of ECG findings occurred following successful therapeutic rewarming.
Implications:
- ECG monitoring is crucial for assessing cardiac involvement in hypothermia.
- Osborn waves serve as an important diagnostic marker for hypothermia.
- Prompt correction of hypothermia is essential for reversing potentially life-threatening cardiac dysrhythmias.
