Abstract
A method for evaluating cardiac diastolic function, which applies to the field of cardiac monitoring. The method comprises: obtaining vibration information of the surface of the thoracic cavity of a subject by means of one or more optical fiber sensors; preprocessing the vibration information to generate hemodynamic related information; performing high-frequency component extraction on the hemodynamic related information to generate high-frequency component information; determining a first feature value and a second feature value based on the hemodynamic related information and the high-frequency component information; generating indicating parameters based on the first feature value and the second feature value, and evaluating the cardiac diastolic function of the subject based on the indicating parameters.
