Implantable Loop Recorders (ILR) are advanced diagnostic tools used to monitor your heart's rhythm over an extended period— especially if you're experiencing symptoms like fainting, dizziness, or unexplained palpitations. While traditional heart monitors, like Holter monitors, are worn externally and can record data for shorter periods, ILRs are designed for long-term monitoring, often up to three years.
The procedure to insert an ILR is minimally invasive and typically performed in the office with local anesthesia. The device is small, about the size of a USB stick, and is placed just beneath the skin of your chest. Once implanted, it continuously records your heart's electrical activity and can capture abnormal rhythms that may not appear during a standard, in-office ECG or other tests.
ILRs are especially useful for diagnosing intermittent heart issues, including arrhythmias that may occur infrequently. The device transmits recorded data to your doctor, allowing real-time monitoring and timely interventions if any concerning patterns are detected. At Heartwise Cardiology, Dr. David Harnick and Dr. Raymonda Rastegar are experienced in using Implantable Loop Recorders to monitor patients' heart health and make accurate, informed decisions regarding treatment.

An Implantable Loop Recorder (ILR) is a small, battery-powered device that continuously monitors your heart's electrical activity. It is placed just under the skin of your chest and records irregular heart rhythms (arrhythmias) over an extended period. The device helps diagnose unexplained fainting, palpitations, and other heart rhythm issues by storing and transmitting data to your doctor for review.
The ILR is implanted during a minor outpatient procedure that typically takes less than 30 minutes. Your doctor will numb the area with a local anesthetic before making a small incision to insert the device just beneath the skin. Most patients experience minimal discomfort during and after the procedure, and recovery is quick, usually allowing you to resume normal activities within a day or two.
An ILR can monitor your heart for up to three years, depending on the device model and battery life. If your doctor determines that the ILR is no longer needed, it can be removed through a simple procedure similar to the implantation process. Some ILRs automatically stop recording and remain in place without causing harm, while others may require removal based on your doctor’s recommendation.
