ASSOCIATION OF DURATION OF TYPE 2 DIABETES MELLITUS WITH HEART RATE VARIABILITY AMONG NEWLY DIAGNOSED PATIENTS

Abstract

AIM:To nd out any correlation of HRVparameters with duration of disease among newly diagnosed type 2 diabetes mellitus. MATERIALS AND METHODS: A cross sectional study was conducted for one year span from September 2020 to August 2021,in the Department of Physiology, R.G. Kar medical college in collaboration with Department of Endocrinology, R.G. Kar Medical College,Kolkata.56 Patients diagnosed to have T2DM within the age group of 30 and 64years (both genders) attending DIABETIC CLINIC run by the Department of Endocrinology at R.G. Kar Medical College and Hospital were screened to the Autonomic Function Research Laboratory of Physiology in the Department of Physiology, R.G. Kar Medical College and Hospital, Kolkata, West Bengal, India. Computer with software for HRV analysis Physiograph Polyrite-D instrument with bio-ampliers, 4channels and accessories(RMS latest software-Version 3.0.16) was used to analyse time domain and frequency domain parameters of short term heart rate variability of 5 minutes duration. RESULTS: Pearson correlation study showed signicant positive correlation of LF:HF ratio with duration of T2DM among newly diagnosed cases and statistically signicant negative correlation was found between duration of T2DM with SDNN. CONCLUSION :we can conclude that duration of disease of diabetes mellitus is associated with sympathovagal imbalance.So CAN screening should be routinely done in all patients even if type 2 diabetes mellitus is newly diagnosed.
