The effects of supraphysiological estrogen levels on ventricular repolarization parameters.

CONCLUSIONS: Supraphysiological estradiol levels that occur during controlled ovarian stimulation causes prolongation in QTc intervals, but this is not at pathological level. Although this prolongation is not significant in healthy individuals, it might increase ventricular arrhythmia risk in patients with congenital long QT syndrome and in patients taking medication that prolongs QT.
