We are still trying to diagnose our family with Long QT Syndrome. We have all had ECGs and Exercise Tests. Our QT intervals are all Borderline. Mine is actually below the borderline but the doctor said that it shortens with age sometimes. The kids are scheduled for Adrenaline Challenge Tests in Calgary. What can you tell me about this test. Is it risky? The doctors have said that it is necessary because the risk of Long QT Syndrome is so great. Also Steven, the 9 year old, has Junctional Escape Rhythms during his standing, hyperventiation, and recovery ECGs. They said that this could interfere with his treatment. Are these rhythms common in children while they are awake. The doctor said that they usually only happen in children while they are sleeping.
Any info would be greatly appreciated.
