Yes I think you should get this carefully checked out; however, I got severe shortness of breath and nearly passed out during and for at least six months after Herceptin. It's a year and two months now since my last dose, and I can exercise and even dance without getting severely short of breath. I think it was side effect -- maybe my heart was stressed. Neither my onc or primary care suggested a cardiologist, so I waited. I'm happy to say the condition has improved, and I trust you will get better too. Still, a visit to the cardiologist can't hurt. I'll visit one myself if I think I need it, whether my doctors recommend it or not.
