Background: Cardiovascular autonomic neuropathy (CAN), a complication of DM, affects the autonomic nerves innervating the heart and can adversely affect cardiac performance. Reduction in HRV is an early manifestation of CAN with parasympathetic loss preceding sympathetic dysfunction. Whether HRV is influenced by prior diabetes treatment or glycemic control in young adults with youth-onset DM is not known. The present study thus aimed at assessing HRV on electrocardiography in young adults with diabetes. Materials & methods: A hospital based observational study was conducted at Department of Medicine of Dr. D.Y. Patil Hospital & Research Centre. 100 diagnosed cases of diabetes for more than 5 years in age less than 45 years were enrolled.. All the patients were subjected to a detailed history taking and physical examination. Patients were then tested for HRV with the use of an ECG generator – Baseline resting ecg for Sinus arrhythmia followed by ECG taken while deep breathing. Results: E:I ratio was abnormal in 29 percent of the patients while HRV was lost in 3 percent of the patients on resting baseline ECG . Conclusion: Early detection of loss of HRV in asymptomatic patients is also important for cardiovascular risk stratification in the diabetic young adults
