I am a 27 year old female who suffers from Panic Disorder. When I was about 22 years old, I held developed PVC's and PAC's. I do not experience them frequently, but when I am going through my PVC phases they last about a week to a month with PVC's happening every hour or so. I recently have noticed that I also get weird string of beats that makes me wonder if I have developed SVT's as well. For example, last night I was laying in my bed, taking my pulse, and my heart would race three beats and then return to normal resting heart rhythm. This past June I wore a 24 hour halter monitor which showed absolutely no arrhythmia's what so ever (figures), did an EKG, and an echo stress test. They said I was completely normal and not to worry about it. I just want to make sure that they did the extent of tests needed to make sure that my heart is healthy. Due to my panic disorder it is hard to believe that there is nothing physically wrong with me, especially since my heart acts like a drummer from a rock band on occasion.
Is there anything I should be worried about, should I be asking for any further tests, or do you guys think these tests were absolutely thorough enough and I should get on with my life?
