Electrocardiographic findings, USG neck and Echocardiography in hypothyroidism

Abstract

Introduction: Hypothyroidism is caused by insufficient secretion of thyroid hormones by the thyroid gland or by the complete loss of its function. The share of hypothyroidism among other endocrine diseases is gradually increasing. Aims :To study electrocardiographic findings, USG neck and echocardiography in hypothyroidism. Materials and Methods:The present study was an observational study included 100 hypothyroid patient for 2 years between January 2019 to December 2020 conducted in the department of General Medicine, Government Medical College,Nizamabad,T.S, Results:Most of cases (58%) were in the age group of 31-40 years and 21-30 years. Mean age score was 35.78 years with standard deviation of 17.41years. There was an overall female preponderance among all age groups. The female population constituted about 84% of the total with female:male ratio of 5.2:1. The BMI of the study population most commonly belong to overweight category (71%) followed by obese (20%) and normal (9%) . Majority of the patient were moderately hypothyroid (51%) ,30% were severely hypothyroid and 19% were mildly hypothyroid. Sinus bradycardia was seen in upto 32% of the patients which was the most common ECG finding , 20%. Patients had normal ECG. The most common USG neck finding in the study population was thyroiditis constitute 31% where as 27% had normal USG neck. Diastolic dysfunction (38%) was the most common 2D echo finding in the study population..Conclusion: This study suggests that it is very important to evaluate patients of primary hypothyroidism for cardiovascular changes so that prior interventions could be performed to improve the clinical outcomes.
