[Cardiovascular response to sympathetic stimulation in normal subjects with or without familial hypertension].

Unlabelled: The aim of our study was to seek out a possible different reactiveness to cardiovascular stimulation tests among normotensives with and without positive family history of essential hypertension. We have studied about 200 inhabitants of Ustica and 49 medicine students, all normotensives according to the World Health Organization and the Joint National Committee criteria.
