My 6yo daughter gets very upset sometimes. You can call it a tantrum, meltdown, violent screaming fit, whatever, but when she gets upset, she is inconsolable and her little heart literally pounds in her chest. I don't know whether I've mentioned this to the psychiatrist she had been seeing or not, our regular doctor is zero help, and we get our first session w/ the OT this week. So I was wondering whether this was a common symptom or something we should talk to a cardiologist about. Anyone?
