Clinical trials: Arrhythmia Ventricular
Premature Ovarian Insufficiency
Ventricular Repolarization in Patients With Premature Ovarian Insufficiency (QTIOP)
Ventricular repolarization, measured by corrected QT interval (QTc), is influenced by sex hormones. A QTc above 460msec predisposes to the risk of "torsades-de-pointes"(TdP).
