While women tend to have a longer QTc interval than men, a value of 500 is abnormal. If it is not explainable by medication effect (quinidine, quinolone antibiotics,other antibiotics, antifungals, etc) it can imply some structural abnormalities of the heart. A cardiologist is best to evaluate and advise you.
