I'd start with your internist/PCP. It's possible to have anxiety and heart issues. Does it feel like it's turning or fluttering when you get the palpitations? If you do, i'd go get checked right away. Thyroid and a number of things can cause that or trigger it (like anxiety). So it doesn't mean it's a heart issue but please get checked. Anxiety can exasperate heart palpitations and vice versa.
