hi i'm new here. would like to from others who suffer from ectopic beats and atrial fibrillation. (af) do they make you feel really awful? mine do. i feel panicky, breathless and feel like i am going to pass out. sometimes i feel as if my heart is going to stop. i am female and 66 years old. i am waiting for an ablation for the af. has any none had this done and if so did it work. i feel my life has lost its quality as i am constantly thinking of my heart. it stops me going to sleep at night. would really like some feedback on this.
