The 5-min Standing Man

The signals presented here have been recorded on a single human healthy volunteer. The procedure was the same for all the signals: 20 min supine rest, followed by 10 min signal recording, 5 min while supine and the following 5 min while standing. On the graphs, the x axis is the time (10 min scale). The 5 min supine period is the left half of the graph while the 5 min standing period is the right half
