Key result
In 22 normal subjects, changes in blood pressure variability in response to psychological stressors were inversely related to resting heart period variability.
Why the study?

Are blood pressure variability responses to psychological stressors inversely related to resting cardiac autonomic control in normal subjects?
Resting cardiac autonomic control is inversely related to blood pressure variability responses to psychological stress, supporting a model of cardiovascular control involving central, baroreflex, and sympathetic mechanisms.
Sloan et al. (1997) conducted an observational in Healthy subjects (n=22). Psychological stressors vs. Resting state was evaluated on Blood pressure variability (BPV) responses to psychological stressors. In 22 normal subjects, changes in blood pressure variability in response to psychological stressors were inversely related to resting heart period variability.
