Ah, you are not alone and I sorry you felt that way. I should have told you that many of the concerns and posts I have read over the years both in the A & P Forum and in this forum are from people with this very same problem. It is natural to feel anxious when we think we may have a heart problem. ((((((((Hugs))))))))).
I wish I could find a post that was from a member who had thousands of PVCs daily and it was documented via the Holter Monitor. Now that would send me into a tailspin.
If your attempts to reassure yourself and to make appropriate lifestyle changes do not give you sufficient relief, you and your doctor may want to consider a trial of drug therapy. JMHO.
Take good care of you and know you are important to us here in the forum so keep on talking with us.
