Pulse waveform analysis and arterial wall properties.
Risk factors for cardiovascular disease mediate their effects by altering the structure, properties, and function of wall and endothelial components of arterial blood vessels.1 The ability to detect and monitor change in the physical properties of arteries, representative of the cumulative and integrated influence of hemodynamic, metabolic, and inflammatory stimuli in impairing arterial wall in...
متن کاملThe dicrotic arterial pulse.
SUMMARY The study consisted of observations on nine male patients with palpable dicrotic carotid pulses. Average patient age was 37 years. All had advanced myocardial failure as evidenced by cardiomegaly and the presence of prominent atrial and ventricular diastolic gallop sounds. Most of these patients were diagnosed as having primary myocardial disease. The indirect carotid pulse was characte...
متن کاملValveless pumping: the reflected pulse wave hypothesis
Valveless pumping refers to nonzero mean flow of fluid within a closed loop of viscoelastic tubing, when a compliant section of the loop is rhythmically compressed at particular frequencies. Valveless pumping is thought to play a role in blood circulation in embryos and in cardiopulmonary resuscitation (CPR). Heretofore, the physical mechanism causing valveless pumping has remained a mystery. W...
متن کاملArterial stiffness: reflections on the arterial pulse.
Arteriosclerosis—arterial stiffening—is the basic cause of isolated systolic hypertension (ISH) and the present epidemic of heart failure in the elderly. Arteriosclerosis is equally important for the development of coronary events, stroke, dementia, and renal failure. The underlying pathology was described by Osler as ‘senile arteriosclerosis’ to distinguish it from essential hypertension (Osle...
متن کاملMeasuring the Pulse of the City through Shared Bicycle Programs
City-wide urban infrastructures are increasingly reliant on networked technology to improve and expand their services. As a side effect of this digitalization, large amounts of data can be sensed and analyzed to uncover patterns of human behavior. In this paper, we sense and analyze data from a new type of urban infrastructure called shared bicycling. We provide a spatio-temporal analysis of si...
