Primary Hyperparathyroidism and Polymorphic Ventricular Tachycardia.

BACKGROUND

Primary hyperparathyroidism is a rare but important cause of ventricular arrhythmias. METHODS AND

RESULTS

The medical records of a patient with primary hyperparathyroidism and polymorphic ventricular tachycardia was reviewed. The patient was serially interviewed and examined before and after parathyroidectomy. A literature search was performed. The association of primary hyperparathyroidism and polymorphic ventricular tachycardia is rare. Hypokalemia and hypomagnesemia occur infrequently in primary hyperparathyroidism.

CONCLUSIONS

The potential for malignant ventricular arrhythmias in the setting of primary hyperparathyroidism must be recognized.
