Borderline Long QT ECG Reading in 9 year old boy

[stevie_wonder]

My 9 year old son was a getting an ECG done because the doc found a heart murmur. The ECG showed Borderline Long QT. Our family doc said the ECG looked normal and that the heart murmur seemed to be gone. He said he probably just had an infection and the Cardiologist said he would see my son in about 4 or 5 weeks to discuss the results of the ECG. I looked at the ECG reading when it printed off the printer. He never mentioned anything to me at the time. At first I wasn’t concerned because of the word Borderline. But I have since discovered (via Internet) that Borderline Long QT should be treated and that he may in fact have Long QT Syndrome. My 19 year old had a near-fatal asthma attack in March of 2006. He was running and remembers everything going black. He needed to have CPR performed by the paramedics. The docs wrote it off as an asthma attack. I was always a little suspicious. There are also my sister, mother, aunt, niece, uncle who have had fainting spells and my aunt died at home at the age of 42 in her sleep. Uncle has had 3 heart attacks plus heart surgery when he was 16 because he collapsed playing hockey. They found a hole in his heart. But symptoms persisted. Please tell me if I should persue this further with another opinion or should I wait the 4 or 5 weeks and see what the cardiologist has to say. Any info would be appreciated.
Thanks in advance

Pursue it.  If your son has symptoms similar to those in his family and there is a history of early death, SEE A SPECIALIST.  If there was nothing in question, I'd probably tell you not to fret, but the borderline long QT warrants some investigation.

Heart attacks aren't the same thing as this.  A heart attack is caused by narrowing arteries and/or blood clots.  Sudden cardiac death is what results from arrhythmias and such.

Was the asthma attack ever substantiated?  I mean, does your son HAVE asthma?

See a specialist, particularly one who specializes in rhythm disorders or a pediatric cardiologist.  Do you live anywhere near Cleveland?  They'd be my first choice.

I took medicine for high blood pressure .But few months ago the doctors here in USA asked me to take medicine.The doctor did a ecg also.Comment was borderline.yesterday I went to the doctor and my BP was very high.The doctor suggested me to go to a cardiologist.Do you think it is necessary to go to a cadiologist.sometimes I feel I am having breathing problem also.

Yes, you should pursue it.  I would see an EP that is associated with the SADS organization.  They would be most familiar with Long QT syndrome.
