Anxiety can affect your body in many different ways. For example, when my anxiety hits I get gastric problems right off the bat, diarrhea and nausea. My heart tends to race a little too. I think it affects many in different manners.
Others complain of their heart racing, numbness in the arm, migraines, chest pressure etc. Your symptoms do sound like anxiety to me. Especially since you have had the tests run and everything is coming out fine. I would talk to the cardiologist about how anxiety can affect your heart if he finds that your heart is healthy.
