Effects of steady hypothermia and normothermia on the electrocardiogram in human poikilothermia.

摘要: The electrocardiographic changes observed in (short-term) induced and accidental hypothermia are well known. We studied the effects of steady mild 4 female patients with poikilothermia. 24h Holter recording revealed during significantly decreased heart rate prolongation QT interval comparison normothermia. During short-term variability circadian rhythm were higher than conclude that our even induces alterations. In disorders thermoregulation one should be on alert for cardiovascular complications, especially cold climates.
