AB Cardiac  rhythm  management  devices  (CRMDs)  are  becoming  increasingly  common  as  our  population  ages  and  indications  for  their  use  broaden.1  These  devices  are  becoming  increasingly  complex.  Single-chamber  devices  with  only  a  pacing  function  have  given  way  to  dual-chamber  devices  with  the  ability  to  sense  and  programmable  features  (e.g.,  automatic  mode  switching  or  rate  responsiveness).  Implantable  cardioverter-defibrillators  (ICD)  have  been  developed  as  primary  and  secondary  prevention  for  sudden  cardiac  death  and  have  a  backup  pacemaker  function.  Biventricular  pacemakers  are  known  as  cardiac  resynchronization  therapy  (CRT).  They  were  developed  to  coordinate  the  action  of  the  right  and  left  ventricles  for  patients  with  reduced  systolic  function  and  delayed  conduction  defined  by  a  wide  QRS.  Most  CRT  devices  have  an  associated  defibrillator  (CRT-D)  since  indications  for  CRT  are  associated  with  a  high  risk  for  ventricular  tachycardia  (VT)  and  ventricular  fibrillation  (VF).
