<p>PROBLEM TO BE SOLVED: To provide a method of indicating intervals of heart beat by indicating intervals of heart beat on a coordinate plane based on biological signals such as electrocardiographic complex and to provide an instrument for indicating intervals of heart beat using the method. SOLUTION: On a coordinate plane where both a vertical axis and a horizontal axis show time of intervals of heart beat, make a basic interval of heart beat as a value on an axis, and make the interval of heart beat that comes one beat ahead or one beat behind of the basic interval of heart beat as a value on the other axis. The basic heart beat data found in a series of heart beat data collected from a subject is displayed on a plot graph showing intervals of heart heat, being shifted at every heart beat and plotted on a coordinate plane. The method of indicating intervals of heart beat and its instrument have a feature that the region where vertexes are distributed on a plot graph showing selected average intervals of heart beat depending on a subject's specific information is superposed on a plot graph showing the intervals of heart beat explained above.</p> |
