Should I Consider An EP Study For WPW If My Only Symptom Is Occasional Rapid Heart Rate?

Hi, I have WPW and my only symptom is a very fast heart rate. It occurs a few times a year, lasts just a few minutes and starts and stops by itself. I read that an ep study can give more information about whats going on. Should I consider having one done or is there no point if I don t have bothersome symptoms as such. Thanks
