I posted a week or so ago when I was diagnosed with pac's and pvc's. I go to the cardiologist on Tuesday but just wanted to know if anyone get these feelings. Sometimes I feel a thump in my chest but most times I just feel a flutter and it's making me very nervous. I know I shouldn't be, but I am. I guess it's just very annoying. Also, does anyone one what premature ventricular repolarization and premature atrial repolarization means. Thank you.
