I've seen ectopics mentioned in quite a few threads since I joined this community but I'm not sure what they are. i'm wondering if they are the heart beat irregularities that i get when it feels as though my heart does a triple thump and feels like a ball bouncing off a wall in my chest. sometimes it's just one bounce and sometimes four. Can anyone enlighten me please. By the way, they seem to happen mostly when I'm lying down.
