Dose dependency of NAD + −induced APD90 reduction in various isolated multicellular preparations of the rat heart. LA – left auricle, RA – right auricle, RV – right ventricle, PV – pulmonary veins. Relative APD90 is expressed in % of control APD90 measured before NAD+ application. * - significant difference of APD90 from the control value, p < 0.05, Wilcoxon test
