Heparin-induced transient prolongation of the QT interval during endovascular embolisation of intracranial aneurysm.
Prolonged QT interval and increased QT(C) dispersion have been described immediately following rupture of intracranial aneurysm, due to increased sympathetic activity. Here, we report a patient with transient prolongation of the QT interval, probably due to heparin-induced hypocalcaemia, which occurred during coiling of a right internal carotid aneurysm, 54 days after ictus. Correction of the hypocalcaemia led to resolution of the electrocardiogram and blood pressure abnormalities.
