METHODS AND SYSTEM FOR OBTAINING A PHYSIOLOGICAL MEASURE FROM A SUBJECT

The invention provides a method for obtaining a physiological measure from a subject, in particular a P-V loop. The method includes obtaining a numerical model of a cardiac system and obtaining, in a non-invasive manner, physiological data from the subject. The numerical model is then updated based on the physiological data. The physiological data is then provided to the updated numerical model and a physiological measure is derived based on an output of the updated numerical model, wherein the physiological measure includes a P-V loop. 本发明提供了一种用于从受试者获得生理测量结果(特别是P-V环)的方法。该方法包括获得心脏系统的数值模型，并且以非侵入性方式从受试者获得生理数据。然后基于生理数据更新数值模型。然后向更新后的数值模型提供生理数据，并且基于更新后的数值模型的输出，导出生理测量结果，其中生理测量结果包括P-V环。
