Answer

Permanent pacemaker implantation may be considered for the following [21] :

  • Neuromuscular diseases such as myotonic muscular dystrophy, Erb dystrophy (limb-girdle muscular dystrophy), and peroneal muscular atrophy with any degree of AV block (including first-degree AV block), with or without symptoms, because there may be unpredictable progression of AV conduction disease
  • AV block in the setting of drug use and/or drug toxicity when the block is expected to recur even after the drug is withdrawn.
