Abstract

Background: The American Diabetes Association (ADA), the European Society of Cardiology, and the European Association for the Study of Diabetes all urge routine ECG monitoring in patients with type 2 diabetes mellitus (T2DM) who have hypertension or another cardiovascular condition (CVD). There is little data on the prevalence of ECG abnormalities in T2DM patients.
Materials and methods: For one year, 100 individuals were studied at Darbhanga Medical College Hospital, Darbhanga, Bihar, divided into diabetes (n=50) and non-diabetes (n=50) groups. Fasting and postprandial blood sugar, glycosylated haemoglobin (HbA1c), lipid profile (fasting and postprandial), electrocardiography (ECG), and treadmill test (TMT) were all measured in all patients.
Results: Both groups had a comparable age and gender distribution. The most prevalent ECG abnormalities in the diabetic group were ST depression and T wave inversion (24%), LAE (20%), LVH (8%), RBBB (4%) and LBBB (4%). In the diabetic group, the majority of patients with aberrant postprandial lipid profiles exhibited positive TMT.
Conclusion: Diabetes patients reported greater ECG abnormalities, and the majority were TMT positive.
