Torsades de Pointes due to multihormonal deficiency induced long QT syndrome

A 70-year-old patient suffering from multihormonal insufficiency presented several episodes of polymorphic ventricular tachycardia Torsades de pointes. A long QT interval was diagnosed which was due to hypoparathyroidism-induced hypocalcaemia refractory to the replacement therapy. Although several antiarrythmic drugs were used, only the administration with magnesium sulfate provided electrical stability. The multihormonal deficiency was due to ‘empty sella turcica syndrome’.
