I get annoyed at dr's period - they lack alot of things that patients need - like 5 minutes to explain things; not reading test results, overlooking things; stereotyping patients instead of treating us as individuals - it's better to be safe with things of the heart just in case - and miss something like they did with me.
I really get upset when reading your post!
I can't understand why your doctor tells you that both your children has LVH without even explaining what LVH is!
And more important:
You can't make the LVH diagnosis based on an EKG. Especially not regarding children. The LVH "diagnosis" on EKG is based on how tall the EKG spikes are, and the formulas are made for adults >35 years, with significantly thicker chest walls (more space between electrodes and heart), and even in adults, the diagnosis must be confirmed by echocardiography.
My EKGs always indicate LVH. My echocardiography does not. When the cardiologist looks at my EKG, he sais: This is a normal phenomenon in young adults, especially if you are a little nervous (I guess the heart "fires" a little harder then).
Of course nothing can be ruled out, and you are completely right to see a cardiologist, I just get so annoyed when I read that doctors throw out a diagnosis without explaining it, especially if it's not necessarily correct.
So sorry I don't have a magic something to give you and your children. The only thing I can add to what has already been said, is somehow for you to remain calm, and reassuring any way you can. I believe you are doing everything you can, and the fact the doctors have allowed that your children continue in their "normal" life except for no physical exertion. I think you can take that into your mind and share it with your daughter to try to help calm her. I am sure your medical advice would have taken immediate action if they believed there was any immediate danger.
Yeah I called her dr and left a message for him to call me back if he can.. I feel so helpless, she keeps telling me and I know she expects me help her or know the answers, but I dont and I feel awful!
If you're unsure, certainly call the dr and let them know.
I'd still get a copy of the reports to read for myself - especially not knowing what exactly is wrong and she's having the episodes again
btw sv means supra ventricle i.e. above the ventricles; quite a few articles and dr's responses here on that also that may help.
Both my children see the same doctor and he has both the ekgs, he said the only thing that is the same is the LVH, my daughter is having another issue in addition to the LVH. In fact when they called me not that long ago they told me the both were on restriction and that they would fax something to the school. I have my daughter laying in my bed now and she keeps telling me her heart is doing it again, I dont know if I should take her back to the ER or what I should do at this point.
I am so sorry to hear this, you really have been bombarded with some major stressors latley :( please take care of yourself.
I would fax or mail a request for those records and your son's - see if there are any similarities. You may want to have a copy of your son's when you take your daughter so you can talk to the cardiologist and he/she can look at that also and vice versa for his appt.
It may be beneficial with what you've said, to see a genetic specialists such as Mayo or Cleveland Clinc - some regular cardiologists miss or overlook genetic things; which I've been told is very easy.
LVH - Left ventricular hypertrophy is a thickening of the wall of the heart's main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The most common cause is high blood pressure, but there are genetic causes also - and depends on what type it is and what is causing it(echo and MRI will be needed to be conclusive) - I have Concentric LVH.
