METHOD AND APPARATUS FOR DRAWING VECTOR CARDIOGRAPHIC LOOP

摘要

A method and apparatus for drawing a vector cardiographic loop. The method comprises: acquiring a known point set of a vector cardiographic loop, wherein the known point set is a set of sampling points obtained by means of sampling the vector cardiographic loop (S101); simulating the contour of the vector cardiographic loop based on the known point set, and using a preset method to add at least one interpolation point between adjacent sampling points, so as to draw the vector cardiographic loop (S102); establishing a unit group composed of the sampling points and an interpolation point set, wherein the interpolation point set is a set of at least one interpolation point located on one side of the sampling points (S103); and determining, based on a display unit of a lacrimal point, a point needing to be displayed, and extracting, according to the point needing to be displayed, at least one interpolation point from an interpolation point set in a unit group corresponding to the point needing to be displayed, so as to draw the lacrimal point, wherein the point needing to be displayed is a sampling point needing to be displayed under the display unit of the lacrimal point (S104). According to the method and apparatus for drawing a vector cardiographic loop, a lacrimal point model can be optimized, the level of drawing a vector cardiographic loop can be improved, and visual misleading of a user can be reduced.
