OBJECTIVE: It is believed that heart rate variability (HRV) has strong prognostic value in elderly. But there are few reports on HRV of healthy longevity. The heart rate variability of Uygur elderly in Hetian, including 108 longevity was studied, and the HRV characters of them were evaluated. METHODS: A total of 250 Uygur subjects ages from 60 to 109 years old in Hetian region were selected as study group and divided into three groups, including Uygur longevity group, Uygur pre-longevity group, and Uygur old group. Forty-two subjects from Han nationality were selected as control. All subjects were physically healthy with no history of hypertension, diabetes, and their routine blood chemistry, electrocardiography did not show any significant abnormalities. Holter records were obtained by using Japan Avionic Delmar Cardiorecorders. Subjects were asked to keep their daily activities during recording. RESULTS: No HRV differences were noticed among Uyghur groups, but the HRV between two nationalities were different. There were day to night and sex differences in Uygur groups. CONCLUSIONS: The unique autonomic nerve balance is one of the causes of longevity in Hetian Uygur elderly.
