title: Quantitative analysis of the carotid sphygmogram in atherosclerosis.
abstract: A study has been made, by means of quantitative analysis, of the changes in the CSG of 355 persons-131 healthy, 112 with ischemic heart disease and 112 with hypertension. The quantitative analysis includes: (1) coefficient of declination, pointing to the declivity of the anacrotic limb; (2) coefficient of propulsion, pointing to the time of formation of the maximum peak and (3) level of indentation, pointing to the height of the valve notch. These 3 indices regularly increase along with progressive induration of the arterial wall and serve as quantitative criteria for a more accurate differentiation of the separate types of CSG used in clinical practice.
