Abstract

A new noninvasive method was previously presented for the measurement of the left ventricular (LV) end-diastolic pressure (EDP) by combining Mirsky's method and the experimentally derived relationship. The eigenfrequency was determined by applying a short-time Fourier transform to the velocity signal on the human heart wall which is transcutaneously measured in vivo by the phased tracking method using ultrasound. In the Letter the authors estimate the elasticity of the heart wall for several human patients.
