A 37 year-old male patient was admitted to the intensive care unit after an out-of-hospital cardiac arrest due to ventricular fibrillation in a course of ST-segment elevation acute coronary syndrome. On admission, the patient was unconscious with
a Glasgow Coma Scale (GCS) score of 5. A percutaneous coronary intervention and mild therapeutic hypothermia (HT), defined as maintaining body temperature between 32°C and 34°C, were performed. During HT on ECG, we observed Osborn waves, which resolved spontaneously after re-warming. After five days of recovery, the patient scored 15 on GCS and did not show any neurological deficits.
