Important Reminders

  • Keep your mobile device powered on at all times. You can let the screen go to sleep (or fade to dark), but do not use the power button on the right side to  turn off the mobile device unless you need to.
  • Charge your mobile device each night using the charging cord.
  • Be sure to place your mobile device within 6 feet (2 meters) of where you sleep, so it can connect to your LUX-Dx™ Insertable Cardiac Monitor (ICM)and send data to your health care team. If you can’t place the mobile devicenear where you sleep, place it within 6 feet of a spot where you spend a considerable amount of time (more than an hour) in the same spot every day.
  • You do not need to bring your mobile device with you during the day, unless instructed to by your health care team.

Not Connected

If you see a screen telling you there is a connection issue, that means your myLUX app can’t connect to your ICM device or to a cellular or Wi-Fi network. This is not a signal that something is wrong with your ICM. You just need to tap the button displayed with the connection message and follow the instructions on the screen until you see a screen confirming your monitoring is up to date.

Recording Your Symptoms

Your health care team will let you know if you need to record symptoms in your myLUX Patient app and which symptoms you should record. If your app doesn’t have a Record Symptoms button, that means your clinic hasn’t enabled this feature.

 If you have been asked to record symptoms in your myLUX app, be sure to record them only when you’re feeling them or immediately afterward

Sending Manual Transmissions

For the most part, the LUX-Dx™ system automatically collects and sends your recorded heart rhythms to your health care team. Occasionally, your care team may also ask you to send a manual transmission, but these should only be sent when you are asked to do so by your health care team.

To Send a Manual Transmission:

  1. Tap the Menu icon (  ) in the upper left corner of your app screen.
  2. Select Manual Transmission. Follow the instructions on the screen.
    NOTE: Connecting to your ICM device may take several minutes. A message will confirm when this is complete.
  3. Tap Done.
