Q

What should be done if the R-wave measures less than 0.2mV when implanting an ICM?

A
  • remove device and reposition at an angle 22 degrees toward the sternum using the same pocket
  • if still not 0.2mV or greater, remove and insert using the 2nd recommend position

Q

What are the 3 abnormal sensing issues that may occur at implant of an ICM?

A
  • inadequate R-Wave amplitude (< 2.0mV)
  • undersensing
  • oversensing

Q

What are the steps to correct an inadequate R-Wave amplitude (<0.2mV) at implant of an ICM?

A
  • reposition device is best option

- if unable to reposition, increase R-Wave sensitivity by reducing the sensing value (lowers the fence)

Q

What are the steps to correct T-wave oversensing at implant of a Reveal LINQ ICM?

A
  • reprogram sensing threshold decay delay
17
Q

What are the steps to correct T-wave oversensing at implant of a LINQ II ICM?

A
  • reprogram T-wave blanking interval
18
Q

What are the steps to correct P-wave oversensing at implant of an ICM?

A
  • reposition the device

- decrease the R-wave sensitivity (increase sensing value)

19
Q

What are the types of abnormal sensing that can occur at implant of an ICM?

A
  • undersensing
  • inadequate R-wave amplitude (<2.0mV)
  • T-wave oversensing
  • P-wave oversensing
