Secondary tachycardi: In your question you have provided your most likely diagnosis - excess heart rate as a compensatory mechanism to blood loss and possibly anemia. Your ob.gyn ought to address your heavy periods if they r causing other organs to compensate. In the interim you ought to stay well hydrated....and you may also consider multivitamin with iron.
