TL;DR: A definitive answer on the role that the analysis of markers of cardiac vagal activity may play in risk stratification of patients with coronary artery disease should be provided by Autonomic Tone and Reflexes After Myocardial Infarction (ATRAMI), an ongoing prospective study.

TL;DR: BRS was assessed by calculating the regression line relating phenylephrine-induced increases in systolic blood pressure to the attendant changes in the RR interval and found that a reduced BRS primarily reflects an impairment in the vagal efferent component of the baroreceptor reflexes.

TL;DR: It is shown that the main differences in spectral power (for both low and high frequency) between and within subjects are caused by changes in the arterial baroreflex gain, particularly for vagal control of heart rate (R-R interval) and left ventricular stroke output.

TL;DR: It is demonstrated that the power of cardiovascular oscillations in the VLF band in awake patients with mild to severe chronic heart failure is greatly increased by the common occurrence of unrecognized irregularity of breathing, which may confound the use of heart rate variability measures as indexes of autonomic tone or prognosis.

TL;DR: In the short term after cardiac transplantation the spectral profile of the rhythm variability of the remnant atrium was not improved, suggesting that parasympathetic withdrawal and sympathetic hyperactivity persist, despite the restoration of ventricular function.
