and those with OHTN, suggesting increased peripheral vascular resistance secondary to heightened sympathetic tone . These assessments are easy to perform in clinical setting and may help in phenotyping ...
rate responses to Valsalva maneuver, deep breathing, and active change of posture, whereas sympathetic vasomotor function was assessed by blood pressure responses to handgrip and standing. At the height ...
The effect of age on autonomic nervous system was assessed at rest and while standing using systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate, and power spectral analysis ...
supplementation with inorganic nitrate and modified by ethnic origin. Caucasian and SE Asian (n = 30 for both), were recruited and subjected to an ‘active stand test’ and brachial artery blood pressure (BP), digit ...
in the neurohormonal regulation of blood pressure and plasma volume. There are close connections between sympathetic activity and renin‐angiotensin system activity at the various levels of regulation (central nervous ...
= 0.55, P = 0.001). Conclusion Post-exercise OI is associated with a 'high basal sympathetic modulation of vasomotor tone in combination with a diminished orthostatic sympathetic response' to resistance ...
Background: The aim of the study was to assess the main determinant of the fall in blood pressure (BP) responsible for the head‐up tilt testing‐induced syncope. Methods and results: The study ...
The aim of the study was to assess the clinical significance of the blood pressure (BP) reaction to standing in 1029 stage I hypertensives. Office BP was measured six times in the supine position ...
of sympathetic vasomotor tone [low frequency component of peak systolic blood pressure variability (LFSBP)]. The results showed a significant main effect for tilt angle for the HR response to HUT, which ...
, the IVC collapsibility index. Averages of three measurements of each variable were used for analysis, if applicable. Arterial stiffness and blood pressure Arterial stiffness, assessed by aortic pulse wave ...
