Significats de vagal tone en anglès

An increase in sympathetic tone coupled with a reduction in vagal tone was found.

High frequency power, a pure measure of vagal tone, was comparable between the two groups.

Conclusions: Low vagal tone is correlated with a poor prognosis in patients with heart failure.

Among patients with similar degrees of heart failure, low vagal tone identifies patients with a poor prognosis.

Rationale: Long-term smoking can lead to changes in autonomic function, including decreased vagal tone and altered stress responses.

An additional contribution of vagal tone to survival could not be shown when sympathetic tone was considered simultaneously.

One interaction between baseline vagal tone and maternal protective overcontrol, predicting social wariness, conformed to the moderation hypothesis.

However, electrophysiologic testing and heart rate variability during 24-h Holter monitoring were indicative of a high vagal tone in both patients.

It not only has multiple interactions with the sympathetic nervous system but also may influence vagal tone directly via angiotensin II.
