Baseline Hemodynamic and Respiratory Parameters for the Protocol with Increasing Stimulation Frequencies (2, 5, 10, and 20 Hz)

Cervical vagus	Left	Right	Left	Right
Pulse duration	0.1 msec	0.1 msec	1.0 msec	1.0 msec
Number of rats	3	4	3	4
HR (bpm)	327 ± 14	323 ± 19	330 ± 6	311 ± 18
MAP (mmHg)	126 ± 12	122 ± 8	121 ± 14	119 ± 7
RF (min−1)	36 ± 3	39 ± 5	36 ± 3	37 ± 4

Baseline values for heart rate (HR), mean arterial blood pressure (MAP), and respiratory frequency (RF) before the beginning of cervical vagal nerve stimulation at different stimulation parameters (left or right cervical vagus nerve, pulse duration: 0.1 ms or 1.0 ms). The stimulation voltage was 3 V. Values are means±SEM. There were no significant differences between groups (independent measures one‐way analysis of variance).
