Parameters of heart rate variability in patients with gastroesophageal reflux disease

The study involved 57 patients with GERD, of whom 26 (45.6%) men and 31 (54.4%) women. The average age of patients is 51.4 ± 8.6 years. Among patients with GERD, the typical course of the disease was observed in 49 people (84.7%), atypical - in 8 people (15.3%). Among atypical manifestations of GERD, cardiac prevailed: 5 people (8.8%) noted the appearance of postprandial chest pain, 2 (3.5%) had complaints of palpitations and interruptions in heart function. In one patient, the clinical manifestation of GERD had a "coma in the throat." According to the endoscopic examination, esophagitis was detected in 9 patients (15.3%). Catarrhal esophagitis was diagnosed in 7 (11.9%) patients, erosive - in 2 (3.4%). The article presents an assessment of the nature of changes in vegetative and temporal parameters of heart rate variability (HRV) over a long period of time in patients with gastroesophageal reflux disease (GERD), describes their dependence on the nature of the predominant reflux, the average daily value of intraesophageal pH, exposure time of acid gastroesophageal reflux, reflux index. Women suffering from GERD are 5.4% higher (p=0.01) than men in the arithmetic mean of the RR intervals, which may indicate a relatively higher risk of various kinds of arrhythmias. Also significantly higher in women were the average values of such indicators as the adequacy of the processes of regulation and the voltage index of regulatory systems by 15.2% (p=0.04) and 24.0% (p=0.04), respectively, indicating a greater impact on the sinus node of the sympathetic division of the vegetative nervous system.
