my son was just diagnosed with WPW after being on Naldolol 20mg for four years due to SVT. previous ecgs were clear of WPW. He is 14 and entering high school, an avid football player. He is scheduled to get an ablation done on Tuesday. I am very anxious and wondering if medication is the better way to go. I have been reading about people who under go ablations and have more problems after it. He has had epsiodes of SVT on the medication but nothing like he has had before.
