I know all about PVC's and the unbearable feeling of helplessness that comes along with them! I was just told less than 2 wks. ago that is what I am experiencing. I saw my family Doc several times for "anxiety." When the meds weren't working, and these things would come out of nowhere, I decided to take my health into my own hands and insisted on seeing a cardiologist. He did an EKG and told me I had PVC's, and seemed very unconcerned. Obviously he has never had to experience these, especially on a DAILY BASIS!! Sometimes they last all day, for up to 8 days or more in a ROW!! I was sure I was dying of heart failure! Sometimes I can't even leave the house because they are so severe and scary! I'm sure worrying about them and obsessing is only making them worse, but I can't help it! They are interfering with my every day activities and even work! The Heart Doc put me on a beta blocker, which slowed my heart rate from about 84 BPM to about 64 BPM, but the palpitations are still there! I know how awful these things can be, and I don't understand why they just started out of nowhere one day! He said I've probably always had them, but I wasn't symptomatic! He also said I will probably ALWAYS have them, apparently they don't just go away!!
