Abstract

Introduction: Heart rate variability is one of the diagnostic tests to assess the autonomic dysfunction in
type 2 Diabetes Mellitus.
Objective: To compare the heart rate variability (HRV) and classical autonomic function tests between
type 2 DM and healthy volunteers.
Materials and Methods: This study was conducted in 30 type 2 Diabetes mellitus patients and 30 healthy
volunteers. Average age of diabetic patients was 48.535.12 (mean SD) and that of volunteers was
47.103.59 (mean SD). ECG recording was done in supine position for 5 minutes in computerized
physiography. HRV analysis was done using Finland software. Classical autonomic function parameters
such as deep breathing difference test, heart rate and blood pressure response to hand grip dynamometer
test and valsalva ratio test were recorded in them.
Results: Statistical analysis was done using student’s t-test. HRV showed statistically significant
impairment between cases and controls (p<0> very significant impairment between cases and controls (p<0> Conclusion: HRV and Classical autonomic function tests reveals autonomic impairment in Type 2 DM,
but classical autonomic function test findings showed very significant (P<0> analysis (P<0>
