imbalance

 [im-bal´ans]
1. dysequilibrium (def. 2).
2. lack of balance; especially lack of balance between muscles, as in insufficiency of ocular muscles.
autonomic imbalance defective coordination between the sympathetic and parasympathetic nervous systems, especially with respect to vasomotor activities.
electrolyte imbalance serum concentrations of an electrolyte that are either higher or lower than normal; see discussion and table under electrolyte.
fluid volume imbalance abnormally decreased or increased fluid volume or rapid shift from one compartment of body fluid to another. See also deficient fluid volume and excess fluid volume.
risk for fluid volume imbalance a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as being at risk for a decrease, increase, or rapid shift from one to the other of intravascular, interstitial, and/or intracellular fluid; this refers to body fluid loss, gain, or both. See also deficient fluid volume and excess fluid volume.
sympathetic imbalance vagotonia.
vasomotor imbalance autonomic imbalance.

Though the observed CV alterations were small in magnitude and thus unlikely to pose direct risks to healthy people, individuals with underlying vulnerable atherosclerotic plaques and/or who are susceptible to heart failure, stroke, or arrhythmias could have the risk for a CV event promoted by the acute changes in BP, heart rate, and autonomic imbalance (Brook et al.
Our results show that rural-origin coarse PM exposure is associated with triggering an acute increase in BP and heart rate, likely via autonomic imbalance.
Thus, based on these data, we assumed that exposure to wDE would not only cause immediate exposure-related physiological changes (not measured) but also sensitize the airway autonomic reflex arc (Figure 4), resulting in autonomic imbalance and increased sensitivity to developing arrhythmia.
This suggests that there may be a common toxicologic mechanism of causing autonomic imbalance by submicrometer particles among various populations.
