Background: In this study 100 cases of thyroid dysfunction were studied for the cardiovascular manifestations. Out of these, 60 cases were of hypothyroidism and 40 cases were of hyperthyroidism. There was no age bar for inclusion in the study. All of these cases were selected from those attending the Endocrinology OPD in IMCHRC Hospital, Indore. Result: In our study most common ECG finding is ST/T changes found in 63.3% of patients. Second most common finding is the Low voltage complex (51.6%) & prolonged QTc interval (38.3%). Sinus bradycardia found in 29.9% of patients. V.P.C. & S.V.P.C. are present in 23.25 and 1.6% cases respectively. In patients with hyperthyroidism most common ECG finding is Sinus tachycardia found in 82.5% of patients. Second most common finding is the prolonged QTc interval (42.5%) and L.V.H. found in (27.5%) cases. ST/T changes found in 15% of patients. Atrial fibrillation found in 10% of cases & V.P.C. & S.V.P.C. had incidence of 7.5% each. Conclusion: In our study most common ECG finding is ST/T changes found in 63.3% of patients. Second most common finding is the Low voltage complex (51.6%) & prolonged QTc interval (38.3%). Sinus bradycardia found in 29.9% of patients. V.P.C. & S.V.P.C. are present in 23.25 and 1.6% cases respectively. Gender wise study of ECG in hypothyroidism revealed 1 case with sinus bradycardia, and 2 cases of ST/T changes, 1 case of LVC, and 1 case of VPC among male patients. In female patients predominant ECG finding was ST/T changes (36 cases) followed by LVC (30 cases) prolonged QTc interval (23 cases), sinus bradycardia (17 cases), 13 cases of VPC and 1 case of SVPC.
