Claims

[Scope of utility model registration request]

Six-axis intersecting coordinates are provided on the board in which the limb leads of the six electrocardiograms in the frontal plane are expressed as the lead axes, and the lead axes of the coordinates are 60 degrees clockwise in the order of the first lead axis, the second lead axis, and the second lead axis. At the same time, the aVR guide axis, aVL guide axis, and aVF guide axis are each displayed at an angle of 120 degrees clockwise from the 1st guide axis in that order, and each guide axis is a positive angle with the center point as the border. The side and the negative side are indicated by distinguishable axes, and a first rotary plate and a second rotary plate are superimposed on the substrate and pivotally connected to each other so as to be freely rotatable about the center point, and the first rotary plate A QRS electric axis quick reference board characterized by displaying a guide pointer and a guide axis display line in a diametrical direction perpendicular to the guide pointer, and displaying an electric axis pointer on a second rotary plate.
