Key result
Mild therapeutic hypothermia in STEMI patients after cardiac arrest was associated with decreased heart rate (P=0.014), QTc prolongation (P=0.005), and Osborn waves in 60% of patients.

Does mild therapeutic hypothermia alter electrocardiographic evolution in patients with STEMI complicated by cardiac arrest?
Mild therapeutic hypothermia in STEMI patients after cardiac arrest causes expected ECG changes like Osborn waves and QTc prolongation, but does not alter the typical electrocardiographic evolution of the infarction.
Dzięcioł et al. (2014) conducted a cohort in ST-elevation myocardial infarction (STEMI) complicated by cardiac arrest (n=20). Mild therapeutic hypothermia vs. No mild therapeutic hypothermia was evaluated on Electrocardiographic (ECG) changes during hypothermia and its influence on ECG evolution. Mild therapeutic hypothermia in STEMI patients after cardiac arrest was associated with decreased heart rate (P=0.014), QTc prolongation (P=0.005), and Osborn waves in 60% of patients.
