摘要：

This paper is a theoretical calculation of the possible pressure distributions inside a ventricle. Assuming a spherical shape and a circular orifice, the potential flow equations are solved using Legendre polynomials. The effects of velocity, acceleration, and gravity are discussed. Using published experimental data, it is found that dynamic pressure effects may amount to 15 mm Hg. Such errors may significantly alter the accuracy of pressure catheterization records. © 1979.
