This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern. Heart Rhythm 2010 Hudzik B, Gasior M. There is marked sinus bradycardia.
