Figure 3. — Time course of heart rate by drug condition (means ± sem) and progesterone levels: A-Low Progesterone; B-High Progesterone/Luteal-Phase women. Heart rates at baseline (–200 minutes) are not significantly different between groups. The nicotine patch significantly increased heart rates during the pre-drinking time period (p<.001). For both groups after the drinking period, the three drug conditions are significantly different from each other (p<.001). The large increase in heart rates at −50 minutes was due to a bathroom break given to all subjects.

a. Heart rate responses in Low Progesterone women to three drug conditions.

b. Heart rate responses in High Progesterone/Luteal-Phase women to three drug conditions.
