JIMENEZ-JAIMEZ, Juan et al. Long - QT Syndrome Secondary to Hypocalcemia. Rev. argent. cardiol. [online]. 2011, vol.79, n.4, pp.365-367. ISSN 1850-3748.

Long-QT syndrome is a congenital or acquired disorder that produces sudden death due to ventricular arrhythmias. Electrolyte disturbances and medications are the most common causes of acquired long-QT syndrome. We describe the case of a patient with long-QT syndrome secondary to hypocalcemia caused by primary hypoparathyroidism. The secondary causes of long-QT syndrome should be thoroughly examined as they are more common than the genetic causes. Also, as they are reversible with adequate etiological treatment, their correct identification avoids unnecessary diagnostic and therapeutic measures.

Keywords : Long-QT syndrome; Hypocalcemia.
