I can certainly relate to your fears. I have these feelings too, and, I , too, have been diagnosed with
PAC's. Mine feel different all the time, sometimes, they feel like little "blips" and others, they feel like my tummy is dropping, sometimes, I get a weird feeling in my tummy, then, my heart will beat real fast for about 10 beats or so, then, it skips a beat and goes back to normal, I seem to get this kind when I am really nervous.
These irregular beats can come in all forms, but, as long as you have been checked out by a doctor, and it looks like you have as you have worn a monitor, and he says all is well, then they are nothing. I know it is easy to say and hard to do, but try not to worry too much, worry only makes them worse, I know, I speak from experience.
This is a great group and there are many folks to help, all of us have and are going through what you are.
