ABSTRACT
In the frame of the multifactorial origin of high blood
pressure, the hypothesis that hypertension may indeed rep-
resent one such alteration, that is at least in a sizeable pro-
portion of the hypertensive population, the rise in blood
pressure depends upon an abnormal autonomic cardiovas-
cular regulation, has long been investigated, although its
experimental confirmation has been far from complete.
Because limitations in our methodological armamentar-
ium have certainly represented one of the major difficulties
encountered along this line of research, it is fortunate that
recent technical advances allowed more and more cogent
evidence in this direction to be collected.
