What did the Dr's tell him or you?  Long QT Syndrome is an autosomal dominant condition, and through mutation scanning ( a blood test) geneticists can determine if and where there is a gene mutation. If Long QT Syndrome is known to occur in the family, a person should strongly consider having the genetic test. For many, though, genetic testing follows an incident or two of fainting spells or if there is a sudden, unexplainable death of an otherwise healthy family member. Additional clinical tests that a referring physician may order include an EKG and a stress test.

Because of its serious implications, it is particularly important for families with inherited Long QT Syndrome to discuss test results and their implications with an experienced genetic counselor along with a cardiologist with experience in Long QT Syndrome management. That said, I would definitely make sure to find out if this was the reason for his sudden cardiac arrest. I can only guess that it is possible that he has LQTS but it would not be appropriate for me to confirm or disregard this as being the cause.
