Yes, I too have them. Scared me to death or at least made me think I was gonna die. I had a different episode with my heart that had me seeing a cardiologist. After that was over and I was on medication for my condition I started getting these heart pauses. It got really, really bad at one point and I wouldn't go to sleep because I was afraid I wouldn't wake up. I spoke to my cardiologist who said this is not a big deal. My heart was in perfect working order and the "PVC'S" were not going to harm me. He said I've probably had them for most of my life but until my episode I just didn't notice them. I have a 4 year old, I was worried about leaving him behind. I made my cardiologist swear that this would not kill me; he actually swore to it. He also recommended I meditate because this could be stress related. Haven't done that BUT since having his word that I would survive they have almost disappeared completely. So stress may be a part of it. You should make an appointment with a Doctor to make sure that it's not anything other than PVC's. Good luck on the smoking - I haven't smoked for 3 1/2 years now and it's so wonderful not have that addiction anymore. Good luck an dlet me know how things work out for you!
