Thoracoscopic sympathectomy increases efferent cardiac vagal activity and baroreceptor sensitivity.
OBJECTIVES Thoracoscopic sympathectomy at levels T2 or T2-T3 is a treatment for focal hyperhidrosis and facial blushing. These levels of the sympathetic trunk innervate the heart, and consequently, the procedure is reported to change the heart rate variability due to changes in efferent cardiac autonomic activity. Our objective was to investigate the effects of thoracoscopic sympathectomy on gl...
متن کاملCardiac vagal efferent activity and heart period in the carotid sinus reflex.
KATONA, PETER G., JAMES W. POITRAS, G. OCTO BARNETT, AND BRIAN S. TERRY. Cardiac vagal eferent activity and heart period in the carotidsinus reflex. Am. J. Physiol. 218(4): 1030-1037. 1970. -The activity of single and multiple cardiac vagal efferent (CVE) fibers was recorded in anesthetized dogs under a variety of conditions. During the inspiratory phase of natural respiration the activity of C...
متن کاملDual vagal cardiac efferent pathways.
THE ANATOMICAL WORK PERFORMED by Cheng and colleagues (2) presented in this issue of the American Journal of PhysiologyRegulatory, Integrative and Comparative Physiology provides evidence for specific innervation patterns arising from select populations of neurons in the medulla oblongata to neurons that are clustered in adjacent regions within a mammalian intrinsic cardiac ganglionated plexus....
متن کاملNonlinearities of the human carotid baroreceptor-cardiac reflex.
Carotid baroreceptors of nine healthy young men and women were stretched or compressed with neck suction or pressure, before and after beta-adrenergic and cholinergic blockade, to evaluate several nonlinearities of sinus node baroreflex responses. Sinus node inhibition was related linearly to the intensity of brief baroreceptor stimuli over a range extending from carotid-distending pressures of...
متن کاملInhibition of Cardiac Sympathetic Afferent Reflex and Sympathetic Activity by Baroreceptor and Vagal Afferent Inputs in Chronic Heart Failure
BACKGROUND Cardiac sympathetic afferent reflex (CSAR) contributes to sympathetic activation and angiotensin II (Ang II) in paraventricular nucleus (PVN) augments the CSAR in vagotomized (VT) and baroreceptor denervated (BD) rats with chronic heart failure (CHF). This study was designed to determine whether it is true in intact (INT) rats with CHF and to determine the effects of cardiac and baro...
