Hypothermia presents with a dynamic J-wave pattern on ECG in an elderly man.
This case report highlights the pathophysiologic basis, evolution, and differential diagnosis of the J-wave pattern on ECG in a patient with hypothermia.
May support dynamic J-wave monitoring for arrhythmia risk now; leaves open prospective validation before practice change.
An 83-year-old man was transferred to the emergency department due to an altered level of consciousness and hypothermia. In this case report, we discuss the pathophysiologic basis, evolution, and differential diagnosis of J-wave pattern on the electrocardiogram.
