Primary hyperaldosteronism presenting as recurrent polymorphic ventricular tachycardia (RCDD code: VI-2)

Abstract

Primary hyperaldosteronism (PH) is a frequently overlooked cause of secondary hypertension mostly due to an aldosterone-producing adrenal adenoma. We report the case of a 48-year-old female who presented with recurrent episodes of polymorphic ventricular tachycardia before an aldosterone-producing adrenal adenoma was diagnosed. Although her past medical history was remarkable for poorly-controlled hypertension since age 30, she had never been examined for secondary causes. The patient underwent adrenalectomy resulting in stabilisation of her clinical condition, although residual hypertension remained. Causes of atypical presentation and diagnostic pitfalls are discussed.
