Hi, I have been diagnosed with PVC's. Over a 10 year period I have had 4 stress tests, 2 of them Echo Stress and several EKG's. There is absolute nothing wrong with my heart. I do occasionally get PVC's. I could be over tired, too much chocolate or sweets, nervous, or hormone related. Lately once a day, maybe twice a day my heart will quiver for just a second. I can feel a funny sensation between my breasts. Has anyone ever had this? Should I be concerned? Thanks.
