Abstract
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.
Claims15
A computer-implemented method for obtaining a physiological measure from a subject, the method comprising:
- obtaining a numerical model of a cardiac system;
- obtaining, in a non-invasive manner, physiological data from the subject;
- updating the numerical model based on the physiological data;
- providing the physiological data to the updated numerical model, the physiological data comprising strain data;
- and
- deriving a physiological measure based on an output of the updated numerical model, the physiological measure comprising a pressure-volume, P-V, loop, and a pressure-strain relationship.
(canceled)
A processing unit for obtaining a physiological measure from a subject, wherein the processing unit is adapted to:
- obtain a numerical model of a cardiac system;
- update the numerical model based on the physiological data;
- provide the physiological data to the updated numerical model, the physiological data comprising strain data;
- and
- derive a physiological measure based on an output of the updated numerical model, wherein the physiological measure comprises a pressure-volume, P-V, loop, and a pressure-strain relationship.
