Electrocardiographic parameters and heart rate variability parameters were studied in female and male undergraduate students. To study ECG and HRV parameters, the ArMaSoft-12-Cardio software module with computer software was used. ECG in three standard leads was recorded in the subjects. HR, duration of intervals, ECG clips and complexes, amplitudes of some clips and angles of ECG electrical axes of the heart were compared in female and male students. ECG parameters were analysed in the second standard lead. In addition, HRV parameters were calculated in the same subjects, which were also compared in subjects of opposite sex. It was revealed that there were no statistically significant sex differences in ECG graph elements and HRV parameters between the subjects of the opposite sex studying at senior courses. HRV parameters in the examined persons of both sexes indicated the predominance of sympathetic influences on heart work. Some smoothing of sex differences on ECG and HRV parameters between the examined subjects, apparently, is explained by different contribution of autonomous nervous system departments to heart control as the age of a person increases. In particular, the increase of parasympathetic influence on cardiac function is observed in female subjects with age.
