Implantable Loop Recorder – ILR

An Implantable Loop Recorder is a small implantable device placed under the skin in your chest and provides long-term monitoring of your heart rhythm.

Common reason for getting an ILR:

  • Atrial fibrillation
  • Unexplained Fainting
  • Unexplained Stroke
  • Heart Palpitations

How does the ILR work?

The ILR is place right underneath the skin and will automatically detect and record abnormal heart rhythms, within certain programmed parameters. The data is stored on the device itself. For the clinic to receive this information, your ILR must be paired with a monitor. The monitor is wireless and automatically sends data over secure internet server to the clinic.

How does the monitor work?

The monitor sends the data stored on your ILR automatically. It uses a cellular signal and a power outlet. Data is transmitted once a day as long as your monitor is plugged in and you are within 6.5 ft when a transmission occurs. The animated display shows the strength of the cellular signal. You do not need wireless internet access or a cellular data plan for the monitor to work. If your monitor detects any abnormal rhythms the clinic will be notified via the website by the automatic transmission. Alerts and monthly summary checks are addressed during business hours: Monday-Friday, 8am-5pm. If no abnormal rhythms were detected, the data is updated, but the clinic is not notified.

How much does the monitoring cost for the ILR?

Your insurance company will be billed per month for the monitoring. Most patients do not have any amount they pay per month and some may have monthly co-pay, each dependent upon your insurance policy.
