Bartter Syndrome Presenting with Torsade De Pointes: A Rare Manifestation

A BSTRACT Bartter syndrome is a rare autosomal recessive disorder involving the renal tubules, resulting in defective salt reabsorption and renal salt wasting. There are five types of Bartter syndrome, which affect different parts of the renal tubules. Most cases of Bartter syndrome present early in infancy with polyuria and dehydration or antenatally with gross polyhydramnios. Type 3 Bartter syndrome, also known as Classic Bartter syndrome, however, can present in the first and second decades of life with symptoms related to the severe hypokalemia, including arrythmias, recurrent vomitings, fatigue, weakness, and rarely cardiomyopathy. We describe one such case of Type 3 Bartter syndrome who presented in early adulthood with palpitations and arrythmias due to severe hypokalemia.
