In order to elucidate the dynamical features of the pulsatile blood flow in largearteries, we propose a soliton theory for a simplified and an idealized model-system ofthe blood motion in large blood vessels. The theory is performed for an infinitelylong, straight, circular, homogeneous thin-walled elastic tube filled with an idealfluid. It is shown the pulse waves of pressure and flow propagating through thearteries can be described as solitary waves excited by cardiac ejections of blood andthe features of the pulse wave such as "peaking" and "steepening" are interpreted inthe viewpoint of soliton. The clinical importance of the "lowest blood pressure" andthe "pulse-pressure", which corresponds to the amplitude of pressure pule-wave, isphysically explained by the formula obtained from our theory.
