FIELD: medicine. ^ SUBSTANCE: invention relates to medicine. The method is carried out by using 10 light emitting diodes, to each of which one of 10 push-buttons corresponds. On the first stage of measurement, light flickers fall on the first light emitting diode with frequency 30 Hz, frequency of each next light emitting diode is increased up to 3 Hz comparing with frequency of the previous light emitting diode. On the second stage of measurement, light flickers fall on the first light emitting diode with frequency 3 Hz less, then frequency of the light emitting diode defined by a probationer on the first stage as the light emitting diode, light flux of which is continuous, frequency of each next light emitting diode is increased to 0.4 Hz comparing with frequency of the previous light emitting diode. On the third stage of measurement, light flickers fall on the first light emitting diode with frequency 0.4 Hz less then frequency of the light emitting diode defined by the probationer on the second stage as the light emitting diode, light flux of which is continuous, frequency of each next light emitting diode is increased to 0.1 Hz comparing with frequency of the previous light emitting diode. The probationer defines light emitting diode, the light flux of which is continuous, and pushes corresponded push-button. The frequency rate of light flickers which is taken as the critical light flicker fusion frequency is fixed. This method allows decreasing of examination time during screening programs or testing by cycle ergometry. ^ EFFECT: time decrease of examination during screening programs or testing by cycle ergometry. ^ 1 dwg, 3 tbl, 1 ex |
