Muscle-nerve sympathetic activity in man. Relationship to blood pressure in resting normo- and hyper-tensive subjects.
1. Simultaneous recordings of multi-unit muscle nerve sympathetic activity and arterial blood pressure were made in 29 subjects, 17 healthy and 12 hypertensive. The neural activity, quantified by counting the number of pulsesynchronous sympathetic bursts in the mean voltage neurogram (burst incidence), was plotted against blood pressure. The effect of spontaneous temporary blood pressure fluctu...
متن کاملSeasonal variation in muscle sympathetic nerve activity
Epidemiologic data suggest there are seasonal variations in the incidence of severe cardiac events with peak levels being evident in the winter. Whether autonomic indices including muscle sympathetic nerve activity (MSNA) vary with season remains unclear. In this report, we tested the hypothesis that resting MSNA varies with the seasons of the year with peak levels evident in the winter. We ana...
متن کاملthe tragedy of modern man in arthur millers world
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
15 صفحه اولA quantitative study of muscle nerve sympathetic activity in resting normotensive and hypertensive subjects.
Recordings of multi-unit sympathetic activity were made from muscle branches of the peroneal or median nerves in 33 healthy and 12 hypertensive subjects resting in the recumbent position. Simultaneous recordings of intra-arterial blood pressure were made on 17 normotensive and all hypertensive subjects. The neural activity, quantified by counting the number of sympathetic pulse-synchronous impu...
متن کاملSpontaneous bursts of muscle sympathetic nerve activity decrease leg vascular conductance in resting humans.
Previous studies in humans attempting to assess sympathetic vascular transduction have related large reflex-mediated increases in muscle sympathetic nerve activity (MSNA) to associated changes in limb vascular resistance. However, such procedures do not provide insight into the ability of MSNA to dynamically control vascular tone on a beat-by-beat basis. Thus we examined the influence of sponta...
