It is estimated that almost one in six people are currently at risk of developing diabetes related complications^(2). This study intends to detect the change in heart rate variability (HRV) in diabetic patients as well as its relationship with cardiac autonomic neuropathy. The present study was conducted on 40 type 2 diabetic patients 20 males and 20 females and 40 age and sex matched controls. ECG was recorded and analysed for HRV. The findings showed significant decrease in LF, HF and total power of the study as compared to controls.  There was no significant difference seen in LF/HF ratio.
