LUX-Dx™ ICM System Overview

If you’ve been experiencing symptoms like fainting, a racing heart, or shortness of breath, your health care team may recommend the LUX-Dx Insertable Cardiac Monitor. Also called an ICM or heart monitor, it’s a small device that monitors and records your heart rhythms.

Watch the video below for a quick overview about the LUX-Dx ICM System and how it works to monitor your heart rhythms.

How Your ICM System Works

It’s important to know that your LUX-Dx ICM doesn’t treat your condition. As you go about your day, it automatically checks for irregular heart rhythms (cardiac arrhythmias) and regularly sends information about your heart rhythms to your health care team over a secure Wi-Fi or cellular network. Your clinic will look at the information and contact you if there is need for further review.

Did You Know?

The LUX-Dx ICM System checks for arrhythmias. That’s when the heart is beating too fast, too slow, or in an irregular pattern. It’s an Insertable Cardiac Monitor, which means it’s used to identify a potential issue, not treat it.

System Parts

Your LUX-Dx ICM System has three main parts:

1. ICM Device

This is a small electronic device about the same length as a paperclip placed just under your skin. It automatically monitors and records information about your heart rhythms—whether you’re near your mobile device or not.

2. myLUX™ Patient App

Your myLUX™ app is pre-installed on a mobile device that you’ll get from your health care team after your insertion procedure. It collects information about heart rhythms stored on your ICM device and automatically sends it to your health care team. Your data is usually sent overnight, without you even noticing. You don’t need to carry your mobile device with you unless your health care team tells you to, but you do need to keep it charged and powered on.

3. Magnet

The magnet helps your myLUX app connect to your ICM device and is used to set up your app. Your health care team will let you know if and how they want you to use the magnet after the initial myLUX app setup.

Important

Your mobile device is not a phone that you can use to make calls, text or browse the internet, even in an emergency. In case of emergency, be sure to call emergency medical services on your regular phone.
