When a patient (age 5-18 years) is scheduled for an ablation at Children's Healthcare of Atlanta, the research coordinator contacts the family prior to the procedure and describes the study to them, details the goals, benefits versus risks, and answers any questions they may have. Written consent is obtained from the parents. Assent is obtained from the child. Both the parent and child are given the age appropriate Peds QL (tm) Pediatric Quality of Life Inventory, version 4.0. The forms are returned to the research coordinator. If the child is ablated, then 5-6 months after the ablation, the same questionnaire is sent to the child and parent. Data are entered into a database.
