[Idiopathic hypocalcemia and ventricular fibrillation: report of a case]

We report a 38-year-old female, with past history of syncope and occasional palpitation, who was admitted to our hospital with relapsing episodes of ventricular fibrillation alternating with relapsing runs of ventricular tachycardia of torsade des pointes type, associated with prolonged OT interval and hypocalcemia. These arrhythmias did not respond to any antiarrhthmic drug, and could only be controlled by the insertion of a temporary pacemaker and the normalization of the levels of ionic calcium.
