supraventricular tachycardia

My son was diagnosed with supraventricular tachycardia at 7 months. He is now 26 months and still having problems. He was poorly controlled on Lanoxin and Inderal so we chose to take him off all meds and only treat the episodes when the occured. The cardiologist refuses to consider that there is any underlying problems such as thyroid and says that his case is perfectly routine. He is still having frequent episodes (3 this month)and goes up to about 220. He shows no signs of distress and a small dose of inderal always stops it.  My question is should we be concerned that he is still having such frequent episodes and is it possible that something more is going on besides a straight forward svt?
