Pedirhythm, an international biennial meeting focused on arrhythmia care for infants, children, and patients of all ages with congenital heart disease, will occur for the tenth time in Boston, MA from September 22-24, 2022, as PedirhythmX. Pedirhythm attracts physicians, fellows in training, nurses, scientists, and industry representatives from across the globe, and has quickly developed into the premier stand-alone scientific meeting for pediatric and congenital electrophysiology. Pedirhythm provides the platform for the world’s top doctors to share advances in clinical and research electrophysiology for children and patients with congenital cardiac disease, and a unique opportunity to connect with experts from the world’s leading academic programs engaged in the practice of pediatric and congenital electrophysiology. Hosted by the Boston Children’s Hospital Benderson Family Heart Center, Pedirhythm is proudly endorsed by the Heart Rhythm Society, the Pediatric and Congenital EP Society, the Association of European Pediatric Cardiology, and the Asia Pacific Heart Rhythm Society.
