Im a 26 year old female 3 months post partum, no insurance, I have PPD and have been on several different antidepressants/ antipsychotics, I have severe anxiety and I am currently on Lexapro and Ativan TID. I have been to the ER several times and they find nothing wrong with my heart, however the EMT's have documented SVT's as well as orthostatic HYPERtension. My eyelis twitch and my eyes dilate when I change positions. Could this be due to anxiety or does it sound cardiac. I have had 2 EKG's in the ER as well as 2 chest X-rays.
