Paroxysmal Supraventricular tachycardia in Hypothyroidism: a Case Report

Abstract

Thyroid disorders, both hyperthyroidism and hypothyroidism, have been known to cause many cardiovascular effects however; hyperthyroidism has been known to be an important factor in the aetiology of paroxysmal supraventricular tachycardias. Here, we report a case of young female who was a known case of hypothyroidism for one year, on thyroxin 25 mcg once a day, presented with acute onset palpitations and diaphoresis with electrocardiography (ECG) findings suggestive of Paroxysmal Supraventricular Tachycardia (PSVT). Since there is a paucity of cases reported on tachyarrhythmias associated with hypothyroidism, we wish to add this rare case to the literature.
