Abstract：Objective To investigate the clinical significance of QT dispersion, heart rate variability and ventricular late potentials in patients with aortic arch calcification maintenance hemodialysis. Methods From January 2014 to December 2017, in the Third Affiliated Hospital of Guangdong Medical University, 52 patients with maintenance hemodialysis were selected, according to whether with or without aortic arch calcification, patients were divided into calcification group (35 cases) and non-calcification group (17 cases). The basic clinical indexes, QT dispersion, heart rate variability index and ventricular late potentials in two groups were compared. Results Compared with the non-calcification group, the average age of the patients in the calcification group was more, the mean duration of dialysis was longer, and the mean pulse pressure difference was higher, the differences were statistically significant (P < 0.05). The QTd, Q-Tcd and E/E' in the calcification group were significantly higher than those in the non-calcification group, the differences were statistically significant (P < 0.05) . There was no significant difference in EF between the two groups (P > 0.05). The LFn value and LF/HF ratio in the calcification group were significantly lower than those in the non-calcification group, the differences were statistically significant (P < 0.05). There was no significant difference in HFn values between the two groups (P > 0.05). Conclusion Maintaining calcification of the aortic arch in hemodialysis patients can causes changes of cardiac QT dispersion, reduced heart rate variability, in order to make a greater likelihood of ventricular late potentials in patients.
