Abstract :

Objectives: Use of corrected QT interval as a diagnostic tool for assessment ofCardiac autonomic neuropathy (CAN) in diabetic patients.Methods: All diabetic patients underwent tests to detect cardiac autonomic neuropathy (CAN) and electrocardiography (ECG) to calculate corrected QT interval.Results: Out of 50 patients 38(76%) were males and 12(24%) were females, Type1 diabetes mellitus16 (32%) and Type2 diabetes mellitus34 (68%). Severe cardiac autonomic neuropathy (CAN) was seen when duration of diabetes was14.92+6.23years, early cardiac autonomic neuropathy (CAN) in 11.54+6.44years and no cardiac autonomic neuropathy (CAN) when diabetes duration was 8.9+5.45years. In severe cardiac autonomic neuropathy (CAN) QTc was 467.14+ 45.44milliseconds, early CAN QTc was420.47+ 55.33milliseconds and in no CAN was378.18+ 38.86 milliseconds.Conclusions: Patients with severe cardiac autonomic neuropathy (CAN) had longer duration of diabetes. Patients with severe CAN had higher levels of fasting blood sugar than patients without CAN. Patients with cardiac autonomic neuropathy (CAN) had significantly prolonged QTc.
