• A quantitative method to analyze mental work such as programming or CAD operation is discussed. The authors are proposing to define an index, named 'RRV', which is a variance of intervals between successive R-spikes in E.C.G. (Electro Cardio Graph). In order to increase the measurement efficiency of RRV and to extend the time range of the measurement, a simple and handy-sized measuring unit is developed. From the results of experiments, it is proved that RRV is closely connected with the conditions of mental work. Under such intensive mental work load as repetitive calculation for a long time, values of RRV of the worker become lower than those under usual mental work load. In addition, other basic characters of RRV, for example, time scale of its dynamic behaviour, are studied. Lastly, as a practical application, RRV is measured during computer programming, and several interesting phenomena are observed.
