Background and Objectives of Study Cardiac abnormalities associated with hypothyroidism attracted great deal of investigational effort. There are only few studies done in our country to assess CVS manifestations in hypothyroid patients. Hypothyroidism is known to cause reversible cardiac dysfunction in humans. This study is aimed at studying the cardiac manifestations of hypothyroidism by ECG and ECHO. Methods The data for this study was collected from 30 patients of hypothyroidism who met with inclusion criteria and exclusion criteria were clinically evaluated and underwent relevant investigations including thyroid profile estimation, cardiac evaluation using ECG and 2DECHO. Results Most cases fell in the age group of 31–40 years. There was an overall female preponderance over all age groups with mean age of 34.6 years. On general examination weight gain and dry skin found in around 76.66% and 63.33% of patients respectively. Goitre was found in 3% of patients. Bradycardia seen in 40% and low voltage complexes seen in 33% of patients. Pericardial effusion seen in 26.7% and diastolic dysfunction seen in 26.67% of patients. Conclusion Among 30 cases of hypothyroidism, pericardial effusion was found in 26.7% patients. Diastolic dysfunction was seen in 26.67%. Thus any unexplained pericardial effusion should be screened for hypothyroidism.
