| Abstract(in English) | Left ventricular (LV) pressure, especially LV end-diastolic pressure, is a significant parameter for the clinical diagnosis of heart diseses. LV pressure is usually measured by the invasive catheterization which inserts catheter to the heart via brachial artery or aorta vessel, although it may cause complications. In this paper, therefore, we estimate the LV end-diastolic pressure, which is caluculated by the LV instantaneous eigenfrequency of a small vibration on the LV wall measured by ultrasound. At the same time, the elastic modulus of the heart wall is noninvasively obtained. |
