I have suffered from anxiety for many years. Last month I had a 24 hr, halter monitor and the dr. said I had episodes of a fast heart rate. She put me on metoprolol succ er .25 mg once a day. This has helped but I am very anxious about taking meds. When I started the meds I was working in school and didn't think much about it, but now that I am off for the summer, I am a little more anxious and have been having an occasional skipped beat when I am not busy. Could this be a result of anxiety? My heart does not race .
