Hi @06dodge and welcome to Mayo Clinic Connect. You will see that I moved your post to a discussion where a couple of members are discussing similar problems. You will also notice that in addition to Depression and Anxiety, I also added your discussion to the Heart Health group too just in case there are members in the heart group that have had palpitations with anxiety.

There are two other discussions that you might want to read just to get an idea of what might be going on
Anxiety and heart palpitations: https://connect.mayoclinic.org/discussion/anxiety-and-heart-palpitations/

Heart palpitations with anxiety?: https://connect.mayoclinic.org/discussion/heart-palpitations-with-anxiety/

I see that you were on Zoloft and then Prozac. Did your doctor give you anything to take for sudden onset anxiety and palpitations?
