Haemodynamic baselines during the two visits
| Visit 1 | Visit 2 | |
|---|---|---|
| Systolic pressure (mmHg) | 125 ± 2 | 121 ± 3 |
| Diastolic pressure (mmHg) | 63 ± 1 | 64 ± 2 |
| Mean blood pressure (mmHg) | 84 ± 1 | 82 ± 3 |
| Heart rate (beats min−1) | 62 ± 1 | 64 ± 2 |
| MSNA (bursts min−1) | 11.8 ± 1.2 | 12.5 ± 2.6 |
| MSNA (units min−1) | 179 ± 25 | 172 ± 29 |
| Respiration (cycles min−1) | 17.4 ± 0.5 | 16. 7 ± 1.3 |
| Subject number | 19 | 7 |
Values are means ±s.e.m. Arterial blood pressures were measured by an automated sphygmomanometer from an upper arm. There is no significant difference in the measurements between the trials.
