My daughter just over a month ago started feelings of a strange sensations in her chest, heavy chest and dizziness which comes on suddenly. I was called to school on a few occassions and 3 weeks ago took her to g.p. He did an exam with EKG all normal and ordered a 48hr EKG. Since then have found my Kardia i bought for myself for palpitaions and have given it to her when she feels symptoms. All readings for her are unclassified with 3 showing possible AFib. I took the AFib recordings to g.p who said it looked like AFib. She did EKG told all normal and told to monitor as we had the Kardia. If we had any more episodes to go to A&E which did happen. At A&E had EKG ect..was told all normal sent to childrens ward. Registrar saw the Kardia printouts was a bit dismissive and said nothing can be done documented as every 12 lead EKG thats done is normal and we were sent home. We are also told there is no consultant peadeatric cardiologist to be referred to. Im starting to doubt the Kardia now but i can't doubt her symptoms. Is it possible for a child of 15 to have AFib? Also just found out there is nothing significant on 24 EKG.
