METHODS AND SYSTEMS FOR MONITORING FUNCTION OF HEART

The invention provides a method for calculating an end-diastolic pressure-volume relationship. The method includes obtaining a cardiac input representing a region of interest, wherein the region of interest comprises a left ventricle and a left atrium of a subject. An end of diastasis volume of the left ventricle is then determined based on the cardiac input, wherein diastasis is a stage of diastole during a heart cycle before atrial contraction. Further, an end of diastasis pressure in the left atrium is determined based on the cardiac input and a linearized ventricular pressure-volume relationship is generated based on the end of diastasis volume of the left ventricle and the end of diastasis pressure in the left atrium. An end-diastolic pressure-volume relationship is then determined based on an end-diastolic volume of the left ventricle and the linearized ventricular pressure-volume relationship. 本发明提供了一种用于计算舒张末期压力-容积关系的方法。所述方法包括获得表示感兴趣区域的心脏输入，其中，所述感兴趣区域包括对象的左心室和左心房。然后基于所述心脏输入来确定所述左心室的心休息期末期容积，其中，心休息期是在心房
