Calculation method and device for quadrant distribution of electrocardio vector rings

The invention discloses a calculation method and device for quadrant distribution of electrocardio vector rings. The method includes the steps that basic data of a to-be-calculated male ring is acquired, and the axis intersection of the to-be-calculated male ring and a coordinate axis is calculated; the axis intersection is inserted into a point data set, the point data set is divided into quadrant point data sets of all quadrants according to a preset rule, and quadrant sub-rings of the to-be-calculated male ring in all the quadrants are formed according to the quadrant point data sets; whether nodes exist on the quadrant sub-rings in all the quadrants or not is judged; if the nodes exist on the quadrant sub-rings, the quadrant sub-rings are divided into at least two non-node sub-rings according to the nodes, and the areas of the non-code sub-rings in all the quadrants are calculated according to a preset algorithm respectively; the areas of the non-node sub-rings in all the quadrantsare accumulated, so that
