Severe hypothermia increases DOR more than therapeutic cooling in canine wedges; leaves open clinical arrhythmogenesis relevance.
Does severe versus therapeutic hypothermia increase transmural dispersion of repolarization and arrhythmogenesis in canine left ventricular wedge preparations?
Severe hypothermia significantly amplifies transmural dispersion of repolarization compared to therapeutic hypothermia, explaining the increased risk of arrhythmogenesis and supporting the safety of clinical therapeutic hypothermia protocols.
