Heart-Rate Variability Effects of β-Adrenoceptor Agonists (Xamoterol, Prenalterol, and Salbutamol) Assessed Nonlinearly with Scatterplots and Sequence Methods

Publikováno v: Journal of Cardiovascular Pharmacology. 33:859-867

Full antagonists of the cardiac beta-adrenoceptor improve heart-rate variability (HRV) in humans; however, partial agonism at the beta2-adrenoceptor has been suggested to decrease HRV. We therefore studied the HRV effects of some partial agonists of

AIMS To examine the impact on heart rate variability (HRV), of agonism or antagonism at the cardiac beta2-adrenoceptor in healthy volunteers, using standard time-domain summary statistics and non-linear methods (scatterplot and quadrant analysis). ME

There is evidence that the processes regulating heart rate variability (HRV) reflect nonlinear complexity and show “chaotic” determinism. Data analyses using nonlinear methods may therefore reveal patterns not apparent with the standard methods f

Autor: Anthony Wright, J. G. Riddell, I. ab I. Davies

Publikováno v: Pain. 52:149-155

The reproducibility of focussed ultrasound-induced intra-articular pain was compared with that of electrically induced cutaneous pain over a period of time by measuring both the evoked potential (EP) amplitude and visual analogue scale (VAS) score. T
