Hi @sqwiz welcome to Mayo Clinic Connect. Thanks for deciding to join the conversation. You will see that I moved your question to a discussion that is already talking about Premature Atrial Contractions and Complexes. I did this so that you can connect with members that are going through your same situation and so you could benefit from what they have already shared and ask any additional questions you may have. People in this group like @danab, @cj66 and @slynnb may have more recommendations.
I thought you might also like to read an article that pertains to your diagnosis.
