Chronic hyperglycaemia of Type 2 diabetes mellitus causes long term damage to heart resulting in coronary artery disease (CAD), myocardial infarction (MI), congestive heart failure (CHF), and sudden death from arrhythmias. AIMS: To study the prevalence of different types of arrhythmias in T2DM, particularly in association with Cardiac Autonomic Neuropathy (CAN). METHODS: A cross-sectional study including 100 patients of Type 2 Diabetes Mellitus (T2DM) presenting with cardiac arrhythmias, was done at our hospital over 2 years. Detailed history along with physical examination and tests for CAN were done. Routine investigations along with echocardiography, stress test, Holter monitoring were done. RESULTS: Sinus Tachycardia (ST) was the commonest arrhythmia, found in 32% of patients. 20% had Complete Heart Block (CHB), 15% had Sinus Bradycardia (SB), and 15% had Atrial Fibrillation (AF). Ventricular Premature Complex (VPC) was found in 10% and 3% had Atrial Premature Complex (APC). 3% had first degree AV block, whereas 1% had Paroxysmal Supra Ventricular Tachycardia (PSVT), and another 1% had Ventricular Tachycardia (VT). Poorly controlled diabetes and co-morbidities was associated with higher incidence of arrhythmias. 62% of patients had prolonged QTc, majority of which had CAN. Most of the patients responded to standard therapy.
