A Case of J Wave Syndrome Due to Severe Hypercalcemia with Ventricular Fibrillation Storm and Successful Treatment of Isoproterenol Infusion

Int Heart J. 2021;62(4):924-926. doi: 10.1536/ihj.20-798.

Abstract

A case of J wave syndrome with ventricular fibrillation (VF) storm and severe hypercalcemia due to primary hyperparathyroidism is presented. VF storm subsided with an isoproterenol infusion. Prominent J waves and a Brugada-like electrocardiogram pattern disappeared after parathyroidectomy. Ventricular tachyarrhythmia was not induced during an electrophysiological study. The patient remained asymptomatic up to the 12-month follow-up.

Keywords: Brugada syndrome; Hyperparathyroidism; Prominent J waves.
