[Osborn wave in normothermic patients?]

Area of Science:

• Cardiology
• Electrophysiology
• Medical Diagnostics

Background:

• Normothermic patients can exhibit electrocardiogram (ECG) changes.
• Osborn waves are typically associated with hypothermia.
• Transient repolarization abnormalities require careful interpretation.

Observation:

• Four cases of normothermic individuals presented with transient ECG changes.
• These changes mimicked the morphology of Osborn waves.
• The observed ECG alterations involved ST segment elevation and S wave merging.

Findings:

• The ECG changes were characterized by ST segment elevation where the S wave merged, causing its disappearance.
• This phenomenon persisted as long as the ST segment elevation was present.
• The precise nature of these waves as true Osborn waves remains uncertain.

Implications:

• Distinguishing these transient changes from true Osborn waves is crucial for accurate diagnosis.
• Further research is needed to understand the underlying mechanisms of these ECG alterations.
• This case series highlights the importance of considering non-hypothermic causes for Osborn wave-like patterns.
