Hello,I am a fem age 38 non smoker/drinker overweight but other than that healthy except for long standing anxiety/panic disorder....I have complained of palps for years-always told anxiety--ignore it--they got worse--more feeling of flip flops and hours of strong forceful beats,recently had 2 24 hour holters 1 event monitor and 1 echo--echo was normal except for slight functional murmur-- valves and all normal--ef 70 %(is that good) monitors showed aprox 50 pac and 12 pvc daily--with one 5 second rhythm disturbance but internist didnt say what kind,,i have become so focused on my heart beat and weird chest feelings that it is affecting my every wakeing thought--i am scared all day long--and often at night--every flip flop i feel i think i will die--then it triggers a panic attack a lot of times,,I realize i dont get many compared to many of you but I am just as scared ,,i took celexa for 7 years and was switched to zoloft 3 weeks ago and 5 days ago started on metaprolol 25 mg a day as i asked doc what may help and he said that would--my palps feel diff lately more often in a row maybe ?? went to er once but after the 1 hour wait heart was calm and ecg normal--ecg in past showed non specific arrythmias and non specefic t wave pattern,i holter showed intermittent bundle block but last 3 showed no bbb,,i live in a small town,do not have a reg doc (mostly go to clinic )and the doc that read my test results was an internist that specialises in cardiology--I am soo confused right now--questions are as follows,,1--should I be scared this will kill me?2-can anxiety/stress cause the pac s and pvc s 3-do I need the metaprolol or are the side effects not worth it--4-ativan seems to help alot should i take that instead and stop the beta??5-do i need a stress test?6-how do i know this is benign and move on with my life ?7-is zoloft safe in a person with pvc and pac s--thank you so very much for any replies and would really love a doctor hear to read this as i am worried about the small town doctor opinions i am getting--sighhh thank you so much...
