Maternal hypothermia from environmental exposure in the third trimester.

Margot Rosenthal, Vanessa Poliquin, Adelicia Yu,

A primigravida at 32 weeks gestation developed hypothermia after prolonged exposure to the elements at -30.0°C. Her core temperature dropped to 29.8°C with associated foetal bradycardia. Passive rewarming was undertaken with forced warm air blankets and warmed IV fluids. The foetal heart rate normalised once normothermia was achieved. Serial foetal ... Read more >>

Atrioventricular block, due to reduced ventricular excitability, causes the depression of fish heart rate in fish at critically high temperatures.

Jaakko Haverinen, Matti Vornanen,

At critically high temperature, cardiac output in fish collapses due to depression of heart rate (bradycardia). However, the cause of bradycardia remains unresolved. To this end rainbow trout (Oncorhynchus mykiss; acclimated at +12°C) were exposed to acute warming, while electrocardiograms were recorded. From +12℃ to +25.3℃, electrical excitation between different ... Read more >>
