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.

Abstract: A cardiac diastolic function assessment method, for use in the field of cardiac monitoring. The method comprises: noninvasively acquiring vibration information of the thoracic body surface of a subject; preprocessing the vibration information to generate hemodynamics-related information; determining a first parameter and a second parameter on the basis of the hemodynamics-related information; generating an indicating parameter on the basis of the first parameter and of the second parameter, and assessing the cardiac diastolic function of the subject on the basis of the indicating parameter.

Abstract: Disclosed is a cardiac diastolic function assessment method applicable to the field of cardiac monitoring. The method comprises: acquiring vibration information of the thoracic cavity body surface of an object in a noninvasive manner; preprocessing the vibration information to generate hemodynamic-related information; determining a target wave group on the basis of the hemodynamic-related information; determining the highest peak on the target wave group, determining a rising edge amplitude before the highest peak as a first characteristic value, and determining, as a second characteristic value, an amplitude between the highest peak and the subsequent lowest valley; and generating an indicating parameter on the basis of the first characteristic value and the second characteristic value, and assessing a cardiac diastolic function of the object on the basis of the indicating parameter.
