Intrarenal autoregulatory mechanisms maintain renal blood flow (RBF) and glomerular
filtration rate (GFR) independent of renal perfusion pressure (RPP) over a defined range (80 …

This review examines how the sympathetic nervous system plays a major role in the
regulation of cardiovascular function over multiple time scales. This is achieved through …

Mayer waves are oscillations of arterial pressure occurring spontaneously in conscious
subjects at a frequency lower than respiration (∼ 0.1 Hz in humans). Mayer waves are …

Altered variability in the cardiovascular system is associated with a range of cardiovascular
diseases and increased mortality. Because blood pressure and heart rate show distinct low …

An ablation catheter comprises a catheter body extending longitudinally between a proximal
end and a distal end along a longitudinal axis; and an ablation element assembly …

An ablation apparatus comprises an ultrasonic transducer which includes a piezoelectric
element having a cylindrical shape; a plurality of external electrodes disposed on the outer …

A catheter apparatus for assessing denervation comprises: an elongated catheter body; a
deployable structure coupled to the catheter body, the deployable structure being …

This review focuses on that most engaging feature of the sympathetic nervous system, its
rhythmicity. In particular examining the nature of sympathetic nerve activity (SNA), its …

We have developed a system for long-term continuous monitoring of cardiovascular
parameters in rabbits living in their home cage to assess what role renal sympathetic nerve …

Blood pressure is well established to contain a potential oscillation between 0.1 and 0.4 Hz,
which is proposed to reflect resonant feedback in the baroreflex loop. A linear feedback …
