Adrenal adenoma presenting with torsade de pointes--a case report.

A case of primary hyperaldosteronism due to an adrenal adenoma with near syncope and torsade de pointes is described. A woman patient had a history of high blood pressure and severe hypokalemia that was the cause of her ventricular arrhythmia, which was controlled by administering potassium supplementation but no antiarrhythmic medication. Adrenal adenoma was identified on axial computerized tomography. This case report suggests that there may be a chance of complete cure from torsade de pointes if the underlying cause of QT prolongation can be identified.
