I think the diagnoses if long QT syndrome is done from more than just one ECG, I would imagine you'd be seen almost immediately at the RCH if he thought it could be. I would have thought a cardiologist would have seen you in emergency at the time. If its only something minor you could be waiting months for an appointment at the RCH, I waited 9 months to get an appt for DD2 for her heart murmur, in that time I sent the referral to MonashHeart and she was seen the same week.
