Requires caution extrapolating to human vessels; leaves open mechanisms sustaining noradrenaline contractions without action potentials.
Noradrenaline-induced contractions in the rabbit anterior mesenteric vein are accompanied by action potentials only during the initial stage of drug action, potentially explaining conflicting reports in vascular electrophysiology.
Cuthbert et al. (1965) studied this question.
