What Causes Skipped Heart Beat And Dizziness With History Of Anxiety?

Hello. I m a 26 year old male in good health. I ve been active for the majority of my life and have lead a relatively healthy life style (minus drinking on the weekends) for most of my life. About a year ago, I was sitting on the couch when all of the sudden I felt my heart skip a beat and I was dizzy for a second. Ever since then I get the same feeling at least once a day, sometime more. I ve also noticed that my pulse will feel stronger at times and I can see it in the center of my throat. I do have a history of anxiety and panic attacks, so I m assuming this is the reason. My biggest concern is that I ve never had these symptoms before. Now I m fixated on it and it seems to happen more and more, especially when I do physical activities and get my heart rate going. I m constantly worried about it. don t have a history of heart disease in my family. Im going to see a GP next week, but I wanted a 2nd opinion. Is this something that I should be worried about?
