Autonomic Dysfunction Heart Rate Variability; Type 2 Diabetes mellitus


Background: T2DM patients' cardiac autonomic function is different. Heart rate variability is diminished (HRV). Reduced HRV causes cardiac autonomic neuropathy and increased risk of SCD. Identifying high-risk T2DM patients can help avoid or postpone T2DM consequences. The Diabetes Risk Score questionnaire was created to analyze the patients.

Aim: To study studied HRV in persons with different T2DM risk.

Methods: Physiology Department conducted this experiment. It is a cross-sectional study involving 60 Patients. The RDS questionnaire will be completed by all participants. The RDS score puts them into Groups A, B, and C. 5 min short-term HRV will be measured in all three groups. The data were analysed using SPSS 23.0. ANOVA was used to compare the groups statistically. The variables were connected using the Pearson correlation test.

Results: The post hoc (Dunn's) test demonstrated that HRV levels were considerably lower in high and moderate risk groups compared to mild risk groups.

Conclusion: HRV levels declined with increased diabetes risk, showing a negative connection.
