| 发明名称 | System and methods for assessing heart function | ||
| 摘要 | Systems and methods can be used to provide an indication of heart function, such as an indication of mechanical function or hemodynamics of the heart, based on electrical data. For example, a method for assessing a function of the heart can include determining a time-based electrical characteristic for a plurality of points distributed across a spatial region of the heart. The plurality of points can be grouped into at least two subsets of points based on at least one of a spatial location for the plurality of points or the time-based electrical characteristics for the plurality of points. An indication of synchrony for the heart can be quantified based on relative analysis of the determined time-based electrical characteristic for each of the at least two subsets of points. | ||

| 主权项 | 1. At least one non-transitory computer readable medium storing instructions executable by at least one processor to cause the at least one processor to perform a method for assessing a function of a patient's heart, the method comprising: determining a time-based electrical characteristic for a plurality of points corresponding to at least one spatial region of the heart based on electrical measurement data, the electrical measurement data for each of the plurality of points being derived from measurements acquired concurrently during a same interval and from a non-invasive arrangement of sensors attached to the patient; grouping the plurality of points into at least two subsets of plural points corresponding to different chambers of the heart based on at least one of a spatial location for each of the plurality of points or the time-based electrical characteristic for each of the plurality of points, wherein each respective subset of plural points represent spatial regions of a given chamber of the heart; and quantifying an indication of synchrony between the different chambers of the heart based on relative analysis of the determined time-based electrical characteristic for each of the at least two subsets of points. | ||
