Introduction
The Autonomic nervous system is the principle way by which the heart rate can be controlled effectively. The integrity of the autonomic control of the cardiovascular system in diabetic patients can be studied by observing the heart rate variability (HRV)
Materials and Method
30 type 1 diabetic patients attending the Diabetology clinic of Stanley Medical College, Chennai and 30 age matched controls were enrolled. Heart rate variability analysis during one minute controlled deep breathing was performed on all the subjects and the results obtained were compared between the groups
Results
HRV analysis in type 1 diabetes mellitus patients show
Significant reduction in SDNN, RMSSD, NN50 and pNN50
Significant reduction of mean RR, HF and HF nu, compared to that of controls
Conclusion
HRV during one minute controlled deep breathing is a simple non invasive test to detect cardiac autonomic neuropathy. Hence HRV db should be recommended as a screening test for diabetes mellitus patients.
