An Implantable Loop Recorder
An implantable loop recorder (ILR) is a small device implanted under the chest's skin to continuously monitor the heart's electrical activity for up to several years. It is used to diagnose and monitor heart rhythm abnormalities that occur infrequently and are difficult to diagnose using other methods, such as an event recorder or a standard electrocardiogram (ECG).
The ILR is about the size of a small computer chip and is implanted under the skin of the chest using a local anesthetic. It has one or two electrodes that are attached to the heart, which continuously monitor the heart's electrical activity. The device stores the data and can transmit it wirelessly to a healthcare professional for analysis.
The ILR is typically used to diagnose and monitor conditions such as atrial fibrillation, bradycardia, tachycardia, and syncope (fainting). It can also be used to evaluate treatments' effectiveness and monitor the progression of heart conditions over time.
The ILR is a safe and effective tool for diagnosing and monitoring heart rhythm abnormalities. Still, it is an invasive procedure that requires a small incision and implantation of a device under the skin. The device may also cause discomfort or irritation at the implantation site.
