The chronaxie values for mammalian ventricles at body temperature range from 0.5 ms (human) to 2.0 to 4.1 ms (dog); this is an 8.2/1 ratio.
Other studies have compared the activation of sensory and motor fibers using electric and magnetic stimulation demonstrated through stimulation of nerve and muscle tissue that magnetic activation of intramuscular nerve fibers in the arm and leg occurs at a lower threshold than for electric stimulation.
