Location of surgery
If below the umbilicus, surgery can be safely performed without reprogramming. Above the umbilicus, electrocautery can cause interference, particularly monopolar.
Timing of interrogation before surgery
For elective surgery, ideal timing of interrogation is within 6 months for ICD and within 6-12 months for pacemaker.
Function of magnet on cardiac devices
ICD
Magnet will turn off anti-tachycardic therapy (i.e. no shock)
Pacemaker
Magnet will convert to asynchronous mode
Combined Pacemaker/ICD
Magnet will turn off anti-tachycardic therapy on ICD but will not affect pacemaker
If a magnet is used, all devices should be reinterrogated as soon as safely possible as the magnet may cause different reprogramming after removal.
