Pediatric arrhythmias present numerous challenges to pediatric cardiologists and other practitioners who see pediatric patients, including pediatricians, family physicians, emergency physicians, residents, fellows, and other clinicians. Arrhythmias in Children: A Case-Based Approach features practical methods for diagnosing and treating arrhythmias in these patients across all settings. Nearly three dozen real-world scenarios are presented, followed by a discussion of the diagnosis, clinical thinking process involved, treatment options, expected outcomes, and how to manage anticipated and unanticipated outcomes. These practical, realistic cases provide a unique and engaging way of approaching these challenging patient scenarios
