Bradycardia / conduction delay
bradycardia · society: ACC/AHA/HRS
Summary
Comprehensive guideline on evaluation and management of adult patients (>18 years) with bradycardia and cardiac conduction delay, including sinus node dysfunction (SND), atrioventricular (AV) block, and intraventricular conduction disorders. Supersedes the 2008 device-based therapy guidelines and 2012 focused update. Emphasizes symptom-rhythm correlation for pacing decisions in SND, mandatory pacing for acquired Mobitz II/high-grade/third-degree AV block regardless of symptoms, screening for sleep apnea when nocturnal bradycardia is found, and use of more physiologic pacing (CRT, His bundle) when significant ventricular pacing is anticipated with LVEF 36-50%.
