When healthy subjects stand up, it is associated with a reduction in cerebral blood velocity and oxygenation although cerebral autoregulation would be considered to prevent a decrease in cerebral perfusion. Aging is associated with a higher incidence

Leg crossing increases arterial pressure and combats symptomatic orthostatic hypotension in patients with sympathetic failure. This study compared the central and cerebrovascular effects of leg crossing in patients with sympathetic failure and health

Stroke volume of the heart and thoracic fluid content during head-up and head-down tilt in humans

Autor: J. J. van Lieshout, F. C. Pott, Niels H. Secher, M.P.M. Harms, M. Jenstrup

Publikováno v: Acta anaesthesiologica Scandinavica, 49(9), 1287-1292. Blackwell Munksgaard

BACKGROUND: The stroke volume (SV) of the heart depends on the diastolic volume but, for the intact organism, central pressures are applied widely to express the filling of the heart. METHODS: This study evaluates the interdependence of SV and thorac

Reconstruction of brachial pressure from finger arterial pressure during orthostasis

Autor: Karel H. Wesseling, Johannes J. van Lieshout, M.P.M. Harms, Lysander W. J. Bogert, F. C. Pott, Niels H. Secher

Publikováno v: Journal of hypertension, 22(10), 1873-1880. Lippincott Williams and Wilkins

INTRODUCTION In patients with recurrent syncope, monitoring of intra-arterial pressure during orthostatic stress testing is recommended because of the potentially sudden and rapid development of hypotension. Replacing brachial arterial pressure (BAP)

Twenty-four-hour non-invasive monitoring of systemic haemodynamics and cerebral blood flow velocity in healthy humans

Autor: M.P.M. Harms, Rogier V. Immink, J. J. van Lieshout, M. Diamant, G. A. Van Montfrans

Publikováno v: Acta Physiologica Scandinavica. 175:1-9

Acute short-term changes in blood pressure (BP) and cardiac output (CO) affect cerebral blood flow (CBF) in healthy subjects. As yet, however, we do not know how spontaneous fluctuations in BP and CO influence cerebral circulation throughout 24 h. We

The relationship between aortic flow and pressure is described by a three-element model of the arterial input impedance, including continuous correction for variations in the diameter and the compliance of the aorta (Modelflow). We computed the aorti

Objectives. We studied the incidence and hemodynamic characteristics of near-fainting under orthostatic stress in healthy children and teenagers. Background. Orthostatic stress testing is increasingly used to identify young subjects with unexplained
