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.
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.

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.
