My 9 year old son had an exercise test done to help diagnose Long QT Syndrome. On the test is showed Junctional escape beats and rhythms. How common are these in children while they are awake. The doctor mentioned AV blocks but I haven't got the results back from the specialists (EPs) who are reading the test results. They are away on holidays for a few days and I am having trouble finding any into on these on the internet.
Any info would be appreciated.
