The article considers the possibility of calculating heart rate variability from heart rate data obtained by filtering high-resolution esophageal manometry signals. The data from a single sensor in the central region of the esophagus were used so that the effect of cardiac activity on the signal was most pronounced. After filtering, a sinusoidal signal was obtained. This signal was processed using a peak detector to calculate the time distance between the extrema. Based on manometry and ECG data, histograms and scattergrams were constructed and the variability parameters were calculated.
