Auricular Acupressure Effect on Autonomic Responses Evoked by a Cold Pressor Test in Healthy Volunteers: A Pilot Study

Figure 4

Pulse rate during the first and second cold pressor test. The figure demonstrates the comparisons of the pulse rates at the corresponding times between two cold pressor tests, the front rectangle is pulse rate at the first cold pressor test, and the back one is the pulse rate at the second cold pressor test. There are a total of 13 comparison times.
