Abstract
To assess the autonomic function of the patients of vertigo, we measured the sensitivity of baroreflex using norepinephrine, to produce the increase of bloodpressure and trinitroglycerin, to produce the decrease of blood pressure. As a result, in the patients of vertigo, parasympathetic nerve activity was hypofunction whatever site they were involved.
In the patients of Meniere's disease, at the time around the attack, at the time near the onset of the disease, at the time of active state of the disease, synpathetic nerve activity was hyperfunction. And positiveness of Schellong's test was thought to be related to the hyperactivity of the baroreflex.
On the other hand, spectral analysis of R-R interval revealed that in the patients of Meniere's disease, the parasynpathetic nerve activity tend to be hypofunction.
