Could be: Related to your anemia. It depends on how low your iron stores are. Hopefully they have performed a pelvic ultrasound to help diagose what is occuring. You possibly will need iron infusions, depending on how low your iron levels are. Make sure to take your iron medication with orange juice to help the absorption. Good luck!

Fibroids?: Dysfunctional uterine bleeding can be caused by uterine fibroids. Get an ultrasound. Large fibroids can often be embolized by a minimally invasive technique to stop this. See a good ob/gyn and a skilled interventional radiologist. Racing heart and dizziness caused by blood loss.

Gynecology: Not sure what led you to a heart work up first and not a gynecology work up and/or a hysterectomy. But, this surely seems like something you should approach your gynecologist about.
