Mood states and impedance cardiography-derived hemodynamics.
OBJECTIVE
This exploratory study investigated the relation between psychological mood states and hemodynamic variables obtained at rest.


METHODS
We measured resting hemodynamic variables using impedance cardiography, blood pressure, heart rate, and the Profile of Mood States (POMS) in 71 participants.


RESULTS
Mood states were not significantly associated with heart rate, systolic, diastolic, or mean arterial pressure. In comparison with these basic measures of physiology, a number of impedance derived measures of hemodynamics were associated with mood states. Log stroke volume was negatively correlated with POMS tension-anxiety (r = -.319, p = .009) and fatigue-inertia (r = -. 316, p = .009). Log cardiac output was negatively associated with fatigue-inertia (r = -.346, p < .01). Log total peripheral vascular resistance was positively correlated with POMS fatigue-inertia (r = .276, p = .024).


CONCLUSIONS
Our findings suggest that mood states are associated with hemodynamic variables underlying blood pressure.
