Clonidine-induced changes in the spectral distribution of heart rate variability correlate with performance on a test of sustained attention
Key result
Clonidine-induced changes in the spectral distribution of heart rate variability strongly correlated with performance on a test of sustained attention.
Why the study?
Does clonidine affect the spectral distribution of heart rate variability and performance on a test of sustained attention?

Implication
Hypothesis-generating for ~0.1 Hz HRV as arousal index; prospective validation required before clinical adoption.

Intervention
Clonidine

Outcome
Spectral distribution of heart rate variability and performance on a test of sustained attentionsurrogate
Spectral analysis of heart rate variability in the ~0.1 Hz range may serve as a physiological index of arousal, as its changes induced by clonidine correlate with sustained attention performance.
Cite This Study
Middleton et al. (1994) studied this question. Clonidine was evaluated on Spectral distribution of heart rate variability and performance on a test of sustained attention. Clonidine-induced changes in the spectral distribution of heart rate variability strongly correlated with performance on a test of sustained attention.
