Research of R-R Interval Recording Sensitivity in Diabetic Autonomic Neuropathy Diagnosis
Istanbul Medical Journal
Objective: This study aimed to evaluate the R-R interval recording sensitivity in the early diagnosis of diabetic autonomic neuropathy (DAN). Methods: Sixty patients who applied to neurology outpatient clinics and were thought to have diabetic polyneuropathy were accepted to the study. The control group was formed by 31 healthy volunteers. The standard nerve conduction study and R-R interval measurements during resting and deep breathing were evaluated in the patient and control groups.
... rol groups. Results: When R-R interval measurements of the patient and control groups during resting and deep breathing were compared, no statistically significant difference between the groups was determined. Conclusion: In the diagnosis of DAN, data about the recording of R-R interval measurements that show heart rate variability in resting and deep breathing as significant was not obtained. In larger patient groups, there is a need for broader studies in which Valsalva maneuver and tilt table test methods are also performed.
