Dear J.D., thank you for your question. If you were not experiencing the symptoms of the fast heart beat while your ECG was being done, then it's unlikely anything abnormal would have shown up on the tracing. Most likely, this is a benign condition, but you could wear a portable heart monitor for 24-48 hours to see if your symptoms could be reproduced while your heart rhythm is being recorded. You may want to talk to your physician about this issue.
I hope you find this information useful. Information provided in the heart forum is for general purposes only. Only your physician can provide specific diagnoses and therapies. Please feel free to write back with additional questions. Good luck!
