Summary

Hypothermia can mimic evolving myocardial infarction on electrocardiograms in accident victims. Prompt rewarming reversed these cardiac changes, highlighting the importance of considering temperature effects.

Area of Science:

  • Emergency Medicine
  • Cardiology
  • Toxicology

Background:

  • Roadside accident victims often present with complex medical conditions.
  • Hypothermia is a significant risk factor in trauma patients, affecting multiple organ systems.
  • Electrocardiographic (ECG) changes can be indicative of various cardiac and non-cardiac pathologies.

Observation:

  • A specific case of a roadside accident victim is presented.
  • The victim exhibited electrocardiographic (ECG) abnormalities.
  • These ECG changes were initially misinterpreted as an evolving myocardial infarction.

Findings:

  • The observed ECG changes were directly attributed to hypothermia, not acute coronary syndrome.
  • Core body rewarming led to a complete reversion of the electrocardiographic abnormalities.

  • This suggests a reversible nature of hypothermia-induced cardiac manifestations.

    • Implications:

    • Clinicians must consider hypothermia in the differential diagnosis of ECG changes in trauma patients, especially in cold environments.
    • Accurate interpretation of ECGs in hypothermic patients is crucial to avoid misdiagnosis and inappropriate treatment.
    • Timely rewarming is essential for reversing potentially life-threatening cardiac complications of hypothermia.
