A study of cardiological autonomic neuropathy in Type 2 Diabetes Mellitus with reference to QT interval for its diagnosis

Background: Presence of cardiac autonomic neuropathy (CAN) is responsible for silent myocardial infarction and sudden death in diabetics. Hence recognizing cardiac dysautonomia early, which is asymptomatic will help to delay or arrest its progression.Methods: A cross-sectional study to evaluate the Prevalence of Cardiovascular Autonomic Neuropathy in Type 2 diabetes and correlate it with duration of Diabetes and to investigate the relationship between cardiac autonomic dysfunction and corrected QT interval.Results: In the study population, the prevalence of definite CAN was 8%, 24% and 58% in group A, B and C respectively. The prevalence of definite CAN increases with increase in duration of diabetes. P value
