Type 2 diabetes is associated with increased risk o f cardiovascular (CV) events, especially in the elderly. The electrocardiography (ECG) remains the most widely used non-invasive method for cardiovascular (CV) risk assessment. Hence, the stu dy aimed to evaluate the prevalence, variants and determinants of ECG abnormalities among older patie nts with type 2 diabetes. A total of 200 participants with type 2 diabetes (46% men) attendi ng diabetes clinics at two referral centres were included. Resting ECG was recorded and the various abnormalities identified; left ventricular hypertrophy (LVH), prolonged QTc, ischaemc heart di sease (IHD), conduction defects, ectopic beats among other aberrations. The abnormalities were rel ated to history, clinical, and biochemical parameters.The mean age and median duration of diab etes were 66.8 years and 20 years respectively. The variants and prevalence of ECG abnormalities de tected were as follows: prolonged QTc (25.5%), T- wave changes (22%), LVH (18.5%), sinus tachycardia (15.5%), IHD (9%), conduction defects (7%) and ectopic beats (4%).ECG abnormalities among older di abetics were high and included prolonged QTc, LVH, IHD and conduction defects, and were more rela ted to blood pressure levels, waist circumference, LDL-cholesterol, than glycaemic control
