Question Title: LONG QT PLUS CARDIONEUROGENIC SYNCOPEForum: The Heart Forum
| |
My son age 11 has experienced several fainting spells throughout his life, usually related to some type of physical trauma, but at other times for no apparent reason. He has tested with a slightly prolonged QT interval from .45 at rest to .47 on the stress test. He also had a positive at 10 minutes, tilt table testing in which his heart went into complete asystole. His cardiologist doesn't feel his fainting spells were cardiac provoked, but were probably from the cardioneurogenic syncope. How can we be sure? I was adopted so don't have entire family history on long QT, possibly on my father's side. My son plays basketball in a local Khoury League and starts his first game today. With this only slightly prolonged QT interval and he is on one/half of a 25 mg. Tinormin daily which he takes for the cardioneurogenic syncope and migraines, should I be concerned about his competition in competitive basketball? His doctor says not to worry, but everything I've read says he should not compete in competitive sports.He is a forward so much running is involved. I would appreciate any information you could provide. My husband doesn't seem to be concerned about this condition, but I want to err on the side of caution.Thank you. --------------------------------------------------------------------------------------------------- I am rather conservative in my beliefs. I would not be enthusiastic about him participating in competitive sports. Regardless of why he is fainting, the fact that it has occurred with physical trauma in the past makes it a possibility in competitive sports. However, I would defer to the cardiologist that knows him best. I hope this has been useful. Feel free to write back with further questions. Good luck.
