Type 3 pattern; early repolarization on all derivations with the highest risk for malignant arrhythmia (Figure 1, 2). The patient was intubated and ventilated mechanically and then transferred to the intensive care unit.
Electrocardiography recorded on admission; Zoomed-in view of the V3-V6 derivations (black arrow).

Type 3 pattern; early repolarization on all derivations with the highest risk for malignant arrhythmia (Figure 1, 2). The patient was intubated and ventilated mechanically and then transferred to the intensive care unit.
Electrocardiography recorded after an 8 hour period: Osborn waves were still present (black arrow) (a). ECG recorded after a 36 hour period: Osborn waves had disappeared (b).

Although the patient had been warmed up to 37.1  C over an 8 hour period, it was observed that the Osborn wave did not recover on ECG (Figure 3a). We observed that the Osborn wave had disappeared on ECG at the end of the 36 hour period (Figure 3b).

Type 2 pattern (Figure 4). The patient was followed-up for one-day in the coronary care unit and supported by nasal oxygen and intravenous serum saline administration.
Electrocardiography recorded after a 12 hour period: Osborn waves were still present (black arrow).
