I am 47 yrs. old and have very heavy periods but don t bleed inbetween cycles. I have had several anxiety attacks and been hospitalized for tachycardia- which they say is all psychological. I wore a Holter monitor for a day and the doc said my heart is fine- i don t have mvp like i thought i did. I am thin . i eat well but i do not exercise like i should. i don t know whether i am outof shape or not - oh, by the way, the doctor said i had 10 pvc s during the course of a day with the holtor monitor on- but when i walk upstairs my heart beats way too fast . , then, it takes too long to come back down. maybe i am out of shape. also, sometimes, i can feel my heart beat skipping a beat.- like maybe i am holding my breath or something. i have 3 children to raise and i want to see them grow up. i am scared i have something really wrong with my heart. they did a stress echo and that, too, was just fine. also, during the second half of my menstrual cycle is when i feel anxious and all this weird stuff with my heart. i take iron when i think about it but probably could take it daily . ( i take ferrous sulfate). i am just so scared something is really wrong and the cardiologist missed it. thank you for your answer. helen bird
