Method and the device of the heart beat coming out quantitative decision by the artery pressure pulse beat ripple mark

摘要

The artery pressure ripple mark, the aorta pressure ripple mark and the carotid artery pressure ripple mark and/or directly or measuring these artery diameter ripple marks indirectly, with the method with the method of calculating aorta flux, of removing the reflected component of the pressure wave, calculating peak contraction phase flux V from amplitude P1 of the central pressure ripple mark making use of formula (i), C is aorta pulse beat flux here.
