Timely recognition and thorough evaluation of pediatric atrioventricular block are critical to identify reversible causes and determine the need for definitive pacemaker placement.
Prompts clinicians to prioritize reversible cause identification in pediatric AV block; leaves open need for prospective studies on evaluation protocols.
PURPOSE OF REVIEW: Pediatric brady-dysrhythmias and conduction disorders are uncommon, but timely recognition and evaluation are critical. This review will highlight the key diagnostic and management steps for first, second, and third-degree atrioventricular heart block in pediatric patients. RECENT FINDINGS: There is a breadth of acquired and often reversible causes of atrioventricular block in childhood. Recent advances in diagnostics and pacing therapies have led to improved outcomes. SUMMARY: A thorough evaluation is required to determine when atrioventricular block requires treatment. In symptomatic or unstable patients, the management should focus on resuscitative measures, diagnostic testing, potential reversible causes, monitoring for progression, cardiac consultation and evaluating the need for definitive pacemaker placement.
