An implantable loop recorder ILR ), also known as insertable cardiac monitor , is a small device the size of a chewing gum wrap or a properly grown USB memory stick under the skin of the chest for cardiac monitoring (ie, to record the electrical activity of the heart).

Operasi
ILR monitors the electrical activity of the heart, continuing to store information in the circular memory ("loop" of the name) as electrocardiograms (ECGs). Abnormal activities such as arrhythmia (irregular heartbeat) are recorded by "freezing" the memory segment for review later. Typically, up to three episodes of abnormal activity can be saved, with the latest episode replacing the oldest.
Recording can be activated in two ways. First, the recording can be activated automatically according to the pre-determined heart rate range and set in the ILR by the physician. If the heart rate falls below, or rises above, the level set, the ILR will record without the patient's knowledge. The second way of ILR records is through the hand-held "patient activator" in which the patient triggers the recording by pressing the button when they see symptoms such as knocking over, dizziness or dizziness. ILR records by "freezing" previous electrical information, during and after symptoms in an electrocardiogram format. Doctors can download and review recorded events during office visits using a special programmer, which looks similar to a laptop computer.

Usage
ILR is a useful diagnostic tool when patients experience symptoms such as syncope (fainting), seizures, recurrent palpitations, dizziness, or dizziness regularly but not often enough to be captured by an external monitor 24 hours or 30 days. Due to long ILR battery life (2 to 3 years), the heart can be monitored for a long time.
Insert
ILR is implanted by an electrophysiologist under local anesthesia. Small incisions (about 3-4 cm or 1.5 inches) are made right next to the sternum below the nipple line, usually on the patient's left side. A bag is made under the skin, and the ILR is placed in a pocket. Patients can go home on the day of the procedure with some activity restrictions. Bruises and discomfort in the implant area may persist for several weeks.
Patients are instructed in the use of the activator, and it is advisable to schedule an appointment with their physician after using it so that information stored in the ILR can be taken for diagnosis.
