Personally, I have never been to a cardiologist and did not know what to expect, even though I thought I prepared myself and questions I had.  I felt a little more detail regarding what was happening to my heart, perhaps charts of the heart, etc. would have been helpful for me.   I felt very overwhelmed after the visit trying to process everything.  I was also given a heart monitor to wear, different than the first one I had, but the person who was giving me instructions talked like I was familiar with it.  I had to share with her that I totally unfamiliar with the monitor I was receiving.
