heart block

[wsmom]

My 12 yr old son has Williams Syndrome and Arnold Chiari Malformation. He had previously been dx with Supra Valvular Aortic Stenosis, etc. He had a 30 day monitor on because of heart racing/ palpitations. His dr did a stress test and his heart rate went immediately to 154, and when he was at rest it didn't go below 130. The dr just sent us for bloodwork...Epeniphrine & NorEpeniphrine levels .  He also has a bluish tint to his lower legs and forearms with white spots-when I pointed this out to his cardiologist she said "oh". What are these blood tests for and what will they tell us about whats going on with my son?

Sorry you haven't gotten any advice.  I read of your son's difficulties with a deep feeling of sympathy, but little or no helpful information.
