TLDR
The use of vasoactive drugs and the analysis of spontaneously occurring changes in blood pressure and heart rate are described.Abstract:
In normal subjects arterial baroreflexes play a key role in short-term blood pressure adjustments to a variety of environmental stresses, thereby maintaining circulatory homeostasis. These responses are mediated by the sympathetic and parasympathetic nervous systems through their effects on heart rate, venous return, contractility and peripheral resistance. The evaluation of baroreflex sensitivity (BRS) has recently found unexpected exploitations as alterations in the baroreflex control of heart rate have been associated with an increased propensity for cardiac mortality and sudden cardiac death [1]. Among several quantitative approaches developed for evaluating BRS including the analysis of reflex responses to pharmacological or mechanical manipulations of baroreceptors, this article describes the use of vasoactive drugs and the analysis of spontaneously occurring changes in blood pressure and heart rate.read more

TL;DR: In CHF patients in sinus rhythm, TF-BRS conveys relevant clinical and prognostic information, but its measurability is markedly affected by ectopic activity, and a new prognostic index can be computed in almost all patients.

Baroreflex mechanisms in major depression
TL;DR: The data indicate that different baroreflex components and mechanisms may be impaired in patients with depression and may contribute to their increased cardiac risk.

Restoration of baroreflex function in patients with end-stage renal disease after renal transplantation
TL;DR: The data show that renal transplantation improves blood pressure and HRV and restores baroreflex function to near normal range on the long-term follow-up and these effects may contribute to the improvement of blood pressure control and survival after successful transplantation.

The repeated sit-to-stand maneuver is a superior method for cardiac baroreflex assessment: a comparison with the modified Oxford method and Valsalva maneuver
TL;DR: Findings indicate the sit-to-stand method is a statistically reliable BRS assessment tool and suitable for the examination of baroreflex hysteresis.

Why is blood pressure so hard to control in patients with type 2 diabetes
TL;DR: The authors focus on the mechanisms of resistance to antihypertensive therapy (particularly for monotherapy with either angiotensin-converting enzyme inhibitors or angiotENSin II antagonists) in the treatment of diabetic hypertension.
