Answer

Permanent pacemaker implantation is not indicated for the following [21] :

  • Asymptomatic first-degree AV block
  • Asymptomatic Mobitz I second-degree AV block at the supra-His (AVN) level or that which is not known to be intra- or infra-Hisian
  • AV block that is expected to resolve and is unlikely to recur (eg, drug toxicity, Lyme disease, transient increases in vagal tone or during hypoxia in sleep apnea syndrome in the absence of symptoms)
