Borderline Long QT ECG Reading in 9 year old boy

My 9 year old son was a getting an ECG done because the doc found a heart murmur. The ECG showed Borderline Long QT.

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.

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.
