  • A secretary will call you with the date and time of your procedure. She will mail you a packet of information about the test and directions to the Electrophysiology Lab (procedure area).
  • In the packet, there should be two packages with chest cleaning wipes in them. There will be a picture and directions on how to use them in the packet.
  • A nurse will call and tell you what medicine you should or should not take before you procedure.
  • If you are having a pacemaker or defibrillator (ICD) put in for the FIRST TIME, you will stay overnight in the hospital. You will likely go home mid-day the next day.
  • If you are having a loop recorder put in, or having your pacemaker/defibrillator(ICD) battery changed, you will go home the same day. You may not drive home, so please arrange a ride. You will likely go home between 12 to 4 PM.
  • You will need to get blood drawn before your procedure. Please get this done 5-12 days before the procedure, if possible. A lab slip should be in the packet that was mailed to your home. If not, please call the secretary at 410-328-7801 and tell her which lab you will go to.
