title: The effect of stimulation frequency on the transmural ventricular monophasic action potential in yellowfin tuna Thunnus albacares.
abstract: Monophasic action potentials (MAPs) were recorded from the spongy and compact layers of the yellowfin tuna Thunnus albacares ventricle as stimulation frequency was increased. MAP duration decreased with increase in stimulation frequency in both the spongy and compact myocardial layers, but no significant difference in MAP duration was observed between the layers.
