BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. Colchicine did not prevent atrial arrhythmia recurrence at 2 weeks (31% versus 32%; hazard ratio [HR], 0.98 [95% CI, 0.59–1.61];P=0.92) Circulation: Arrhythmia and Electrophysiology, Ahead of Print. 2.02];P=0.89).

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. No ischemic ST changes.

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.

Another frequent feature of hypothermia is atrial fibrillation (not seen in this case) Core temperature of this patient was 29,5 Celsius. Prominent J waves of this morphology thus are called Osborn waves. Severe hypothermia not uncommonly has accompanying T waves inversions. Troponins were negative in serial blood tests.
