TLDR
Use of harmonic analysis enabled cardiac and vascular factors determining pulse contour to be distinguished and differences in ventricular ejection were the most important cause of differences in the relationship of the brachial to the aortic pulse.Abstract:
Pressure waves were recorded simultaneously in the aortic arch and brachial artery of 32 patients during diagnostic catheterization. Use of harmonic analysis enabled cardiac and vascular factors determining pulse contour to be distinguished. Differences in ventricular ejection were the most important cause of differences in the relationship of the brachial to the aortic pulse.read more

Prospective Evaluation of a Method for Estimating Ascending Aortic Pressure From the Radial Artery Pressure Waveform
TL;DR: Aortic pressure pulse waves, generated from the radial pulse, showed agreement with the measured aortic pulse waves with respect to systolic, diastolic, pulse, and mean pressures, with mean differences <1 mm Hg.

Effect of age and high blood pressure on baroreflex sensitivity in man.
TL;DR: Eight subjects who had normal blood pressure at the time of testing but whose pressure had been elevated in the past, had reflex sensitivities significantly less than expected in persons of the same age and mean arterial pressure.

An analysis of the relationship between central aortic and peripheral upper limb pressure waves in man
TL;DR: In adult humans a single generalized TF can be used with acceptable accuracy to determine central from peripheral pressure under different conditions, as indicated by results of pooled extraction of BATF and RATF.

Pulse wave analysis.
TL;DR: Analysis of the arterial pulse is now regaining favour as limitations of the cuff sphygmomanometer are better recognized and pressure pulse wave analysis now permits more accurate diagnosis and more logical therapy than was ever possible in the past.

Mechanical Principles in Arterial Disease
TL;DR: Those recent advances in mechanical science that are as important and as far-reaching as those in chemical and molecular science but that have not yet been widely applied to assessment of cardiovascular function and disease are considered.
