Progressive development of giant J wave and extreme prolongation of QT interval in induced hypothermia
Abstract
The appearance of J waves is the most common event observed in the electrocardiogram of a patient with hypothermia. We report the case of 47 years-old man, who underwent cardiac arrest using hypothermia for cardiac surgery. In the electrocardiographic tracing the progressive development of giant J waves is evident. These waves can mimic acute myocardial infarction and are considered a predictor of arrhythmogenesis.Downloads
