  1. Induction parameters represent minimal cycle lengths of basic stimuli and extrastimuli. In each animal and condition was EP protocol made three times. NT indicates normothermia; HT, after reaching the core temperature of 32°C; HT60, after 60 minutes of stable hypothermia. ARP indicates the achievement of absolute refractory period; NS, statistically non-significant; ***P = 0.0001.
