Summary: This week we review a recent work from the team at NY Presbyterian on SVT and a possible role it may rarely play in sudden cardiac arrest in children. When a patient does not have an obvious cause of arrest, is SVT a possible etiology and should invasive EP testing be considered? We speak with the senior author of this work, Dr. Leonardo Liberman about his thoughts on SVT as a possible cause of arrest and who amongst the many non-pre-excited SVT patients are perhaps 'higher risk'. doi: 10.1007/s00246-021-02720-z
