Detailed history: It sounds like you have already had testing. These little text boxes are not big enough to go through all the details, which is what a doctor would need to be able to help. Since there are many kinds of arrhythmia, I would want to see the raw data. You might consider a second opinion inbox consult here on HealthTap where you can share the records of your tests and have them reviewed.
