Abstract

The authors present a new noninvasive method for measurement of the left ventricular (LV) end diastolic pressure by combining Mirsky's method and the experimentally derived relationship among the elasticity of the LV wall, the LV sizes and the LV instantaneous mode-2 eigenfrequency. The LV instantaneous eigenfrequency is selectively determined from the time-frequency distribution obtained by applying the wavelet transform (WT) to the nonstationary vibration on the heart wall.
