Mobitz type II second-degree AV block: Identifying candidates for permanent pacemaker placement

This algorithm is an aid to identifying which patients with Mobitz type II second-degree AV block require a permanent pacemaker. Patients with persistent Mobitz type II second-degree AV block are at high risk for progressing to symptomatic Mobitz type II second-degree AV block or complete heart block and therefore are candidates for permanent pacemaker placement. Dual-chamber (AV) pacing is generally preferred to maintain AV synchrony. For additional details, refer to UpToDate content on management of Mobitz type II second-degree AV block.
