Lead quality problems

The following table describes different lead quality problems and possible actions to try to resolve this:

ConditionPossible Causes
Actions
Bad signal
  • Poor electrode contact with skin
  • Not all electrodes are touching
Make sure FX+ is fitting tightly and that all electrodes are touching the skin
Wandering baseline (an upward and downward fluctuation of the waveforms)
  • Electrodes that are dirty, loose, or positioned on a bony area.
  • Oily skin or body lotions
  • Rising and falling of chest during rapid or apprehensive breathing.
  • Not all electrodes are touching
  • Clean skin with alcohol or acetone
  • Reposition FX+ higher (or lower) on the chest so that all electrodes are touching. User should relax
  • If wandering baseline persists, go to Settings and ensure Baseline filter is turned on
Muscle tremor interference (random irregular voltage superimposed on the waveforms). May resemble or coincide with AC interference
  • User is uncomfortable, tense, and nervous.
  • User is cold and shivering.
  • FX+ strap is too tight
  • Not all electrodes are touching.
  • Improperly grounded electrical outlet nearby.
  • Incorrect AC filter frequency setting or AC filter is turned off.
AC interference
(even-peaked, regular voltage superimposed on the waveforms). May resemble or coincide with muscle tremor interference
  • Electrodes that are dirty, loose, or positioned on a bony area.
  • Patient touching any metal objects.
  • Electrical devices in the immediate area, lighting, concealed wiring in walls or floors.
  • Users should get comfortable.
  • Ensure that all electrodes are touching the skin.
  • If interference still persists, the problem is probably electrical in nature. See the following suggestions for reducing AC interference.
  • Ensure that all electrodes are touching the skin.
  • Verify that the user is not touching any metal.
  • Try moving to another room.
  • If possible, unplug electrical devices in the immediate area.
  • If interference still persists, the noise may be caused by other equipment in the room or by poorly grounded power lines.
