Figure 3. Representative tracing of heart rate (HR), MSNA and arterial blood pressure (BP) obtained from the same subject as in Fig. 1 during the second visit.

Pre-Infusion: 3 min period just before the onset of the saline infusion. The interval between the wrap and the infusion during the second visit was much longer than during the first visit. From the onset of the occlusion, the Pre-Infusion period was at the approximate same time when the infusion was performed in the first visit. After the end of the infusion, circulatory occlusion was maintained for 10 min before the cuff was deflated.
