During their time in hibernation, an American black bear's heart rate drops from 40 to 50 beats per minute to 8 beats per minute, and the metabolic rate can drop to a quarter of the bear's (nonhibernating) basal metabolic rate. These reductions in metabolic rate and heart rate do not appear to decrease the bear's ability to heal injuries during ...
The Bears rushed over an AED machine in about 30 or 40 seconds, according to Roth. “We placed the pads on his chest,” Roth said. “The AED identified that he was in a rhythm and needed to be ...
The heart rate variability only increases around three weeks before arousal and the bears only leave their den once outside temperatures are at their lower critical temperature. These findings suggest that bears are thermoconforming and bear hibernation is driven by environmental cues, but arousal is driven by physiological cues.
Commotio cordis (Latin, "agitation / disruption of the heart") is a rare disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart (the precordial region) at a critical instant during the cycle of a heartbeat. [1]

“Folks can do 30 seconds and multiply it by two, 20 seconds multiplied by three,” Ebinger says. “You want that heart rate to be regular, kind of like a metronome.
The technique is done by tightening the skeletal muscles for about 15 seconds when the exposure occurs and then slowing releasing them. [21] This is then repeated every 30 seconds for a few minutes. [21] Because vasovagal syncope causes a decrease in blood pressure, relaxing the entire body as a mode of avoidance is not favorable. [19]
