Clinical pearls from this deck

• Exertional syncope means collapse while the child is still exercising. It is the red flag of this episode.
• An inherited arrhythmia syndrome is a genetic fault in a structurally normal heart.

The twelve worked cases in this deck, with the images and the full explanation of every option, are part of Pediatric Case Review membership. See what is included.
