This week we replay an episode from 2 years ago on postoperative ectopic atrial tachycardia (EAT) following congenital heart surgery in children. Are there risk factors for this arrhythmia and are any modifiable? What is the 'go to' therapy used by the electrophysiologists at Children's LA for the acute and chronic treatment of this arrhythmia in the postoperative period? Is the presence of EAT in a postoperative congenital heart patient a marker for a worse outcome? These are amongst the questions posed to Children's of Los Angeles pediatric electrophysiologist, Dr. Jonathan Uniat.
