Thank you so much for your reply!!
Because all of this is new to me, I am not sure I know the answers and I know all of the correct terminology to use.....but I will try.
From what I understand they basically did the EP study while he was in his arrhythmia...in the ICU. They were unable to diagnosis him until they placed an electrode down his nose and throat and were able to see the backside of his heart. I believe that they gave him a dose of 6mg and 12mg of Adenocard on the medi-flight and then another round in the ICU while they were doing the EP study, which basically told them that it wasn't SVT. It was procainamide that broke the arrhythmia and he went back into the normal rate.
From what the dr. said yesterday they feel like it (the spot of dysfunction) is located on the back wall of the left ventricle...if that makes sense. The dr. also said that this type is very rare (especially in young healthy individuals) and its hard to trigger or predict so he might could play sports and never have another one or might be sitting in class and have an episode....who knows!! But typically things like adrenaline or stressing your heart during sports can trigger them so better be safe than sorry.
I know that his echo was good...no abnormalities but I don't think they told me anything about his resting EKG. I will ask.
I think more than anything I am looking for information and what other people have experienced. I am trying to compile a list of questions to have answered before we make our final decision. Thank so for your help and I will try and post a revised copy in the expert section and see what information I can gather there.
THANKS AGAIN
Hello.
I'm really sorry this happened to him.
You've asked this question in the heart rhythm medical community, and unfortunately there are likely no doctors here to answer your question (I know that a few of them sign up here as community members, but that's uncommon and I haven't seen them for a long time.) Your question is complicated and I think it should be answered by a medical professional, which I'm unfortunately not.
I have some thoughts, but I wouldn't make any decisions based on them.
Sustained VT in young boys (as far as I know) usually origin from the right ventricle, but it may also origin from the left fascicle in the left ventricle, though more uncommon. I think they still are fairly benign considering the risk of degrading to ventricular fibrillation, but this is of course a detail you need to ask a cardiologist or electrophysiologist.
If activities / sports are restricted, there is a reason to believe the doctors think adrenaline is a trigger. There are a few conditions where adrenaline may provoke VT, some of them benign, but one of them is inherited and dangerous, but that would present with runs of polymorphic VT (usually from the right ventricle), which is not the case here, and it would not be tolerated so well. I guess that's ruled out here. I guess his resting EKG and echocardiography didn't reveal any abnormalities.
I hope the doctors informed you if the prognosis is serious or not.
I can't answer your specific questions, but I guess it's not acceptable for a young boy to not be able to have an active lifestyle. Which means something must be done. An EP study is as far as I know a low risk procedure. If the EP study fails, and doctors are still unable to find a cause, I think there is a possibility to implant an ICD.
Please keep us updated, and good luck to both of you.
