Electrocardiographic changes during induced therapeutic hypothermia in comatose survivors after cardiac arrest

Figure 2 Electrocardiograms in lead II from the same patient. Reversible prolongation of all electrocardiograms (ECG) intervals may be observed. A: ECG at admission, core temperature was 35.9 °C; B: ECG at peak hypothermia, 33 °C. Osborn or J wave is marked with a black arrow; C: ECG after rewarming, core temperature was 36.4 °C.
