Long-term monitoring for peace of mind

An implantable loop recorder (ILR) is a small device placed under your chest skin that continuously monitors your heart for up to three years. It helps your healthcare team detect irregular heartbeats that other devices might miss.

Why It’s Used

• Irregular heartbeat (arrhythmia)
• Unexplained fainting
• Stroke of unknown cause

The ILR provides important information to help diagnose and manage heart conditions.

What to Expect

• Procedure: Minor in-office surgery with local numbing; device placed under the skin
• Aftercare: Monitor your incision, avoid strenuous activity, and use the bedside transmitter to send data automatically
• Follow-Up: Checkups once or twice a year, with results shared by your CASL Health team

Safety

• Generally safe; minor risks include bleeding or infection
• MRI-safe—always inform your healthcare providers
• Carry your device ID card for security screenings
