Temperature effects on the Na and Ca currents in rat and hedgehog ventricular muscle
B Liu, P Arlock, B Wohlfart, BW Johansson - Cryobiology, 1991 - Elsevier
Cardiac transmembrane potentials and Na and Ca currents were recorded at different
temperatures in rat and hedgehog ventricular muscle. At 35° C in both species resting
potential was about− 80 mV and upstroke velocity (V ̇ max) of the action potential above
100 V s. The shape of the action p in hedgehog ventricular cells at 35° C was similar to that
in the rat showing a fast repolarization phase. When temperature was decreased, the
membrane resting potential depolarized and action potential amplitude and V ̇ max …
