One of my friends has currently been having some puzzling heart problems. She would be sitting in class, and all of a sudden her hear would race. She would immediately report to the infirmary, where the nurse would take her heart beat into record. I think the highest it ever was was pushing 120, almost into 130. It wasn't like she was doing anything physically strenuous. The only other symptom was a slight tingly sensation in her face, no specific part just all over. If anyone has any possible diagnosis, I would greatly appreciate it. Thanks for your help. If it would help all her gender is female, and her age is 13.
