Electrophysiological characteristics of the rat azygos vein under electrical pacing and adrenergic stimulation

Table 1 The occurrence of spontaneous action potentials (SAP) in the rat azygos vein under basal conditions and under the adrenergic stimulation with the application of noradrenaline (NA), phenylephrine (PHE), and isoproterenol (ISO)

	SAP occurrence	Total number of preparations	% of SAP occurrence
Basal conditions	0	44	0
NA	7	21	33.33
PHE	1	9	11.11
ISO	0	8	0

The first column represents the number of experiments in which SAP were observed, the second column the total number of preparations in each condition, and the third column the percentage of preparations with SAP of the total number of preparations in each condition
