Schedule Your Appointment With a Cardiologist in Phoenix Unlike a pacemaker, no leads or electrodes are necessary with an ILR. The device is inserted beneath the skin through this incision. During the ILR placement procedure, a small incision is made to the immediate left of the breastbone. It can be performed under local or general anesthesia. How is an implantable loop recorder placed?ĭevice implantation is a simple outpatient procedure. Any information recorded – whether manually or automatically – can be accessed by your cardiologist. If you begin to feel symptoms, you can hold a special device over the implantable loop recorder to begin recording. When the device is placed, your cardiologist will program it to begin recording if the heart rate drops below a certain rate. How does an implantable loop recorder work?Īn ILR device can record heart rate one of two ways. ILR devices are typically given to patients who experience symptoms that could be heart-related, such as fainting, lightheadedness, dizziness, seizure, and frequent palpitations, but do not experience symptoms with enough regularity that they can be captured by a 24-hour to 30-day Holter monitor. One of the main differences, however, is that the ILR does not regulate heart rate. The device is somewhat similar to a pacemaker. What is an implantable loop recorder?Īn implantable loop recorder (ILR) (also known as a cardiac event recorder) is a device that records electrical activity in a patient’s heart. Your cardiologist at Phoenix Heart Center can tell you more. However, routine pacemaker evaluations and occasional battery replacements are still necessary. This reduces the number of trips patients with pacemakers have to make to their physician’s office. Many pacemakers can transmit patient information wirelessly to the cardiologist. If the interventionist is satisfied with the results, then the incision may be closed and covered with a bandage or dressing. The device may be tested again at this time. Next, the physician inserts the pulse generator device just below the collarbone, and the lead wires are attached to the generator. Once in place, the physician will test the lead wires to ensure proper placement. Using advanced imaging technology, the physician guides the lead wires through the heart into the correct chamber. ![]() During the procedure, a small incision is made on the chest through which the device’s lead wires are inserted. The procedure is done while the patient is awake. Pacemaker implantation is typically performed as an outpatient surgery. The electrode has two functions: one, to monitor heart rate and relay this information back to the device two, to take over pumping function if heart rate drops below a pre-set BPM threshold. The electrode is attached to the heart’s wall. Depending on the patient’s heart condition, these electrode-tipped leads may be placed in the heart’s upper chamber, lower chamber, or both. The device’s leads, thin insulated wires, run from the generator through a vein and into the heart. The pulse generator device is usually placed just beneath the collarbone. Other reasons for needing a pacemaker:Ī pacemaker consists of a pulse generator, a lead (sometimes more than one), and one electrode for each lead. A pacemaker is used to stabilize this overcorrection. The therapy slows down the patient’s heart rate too much. In many cases, patients with AF receive a treatment, such as catheter ablation or medication. However, even patients with atrial fibrillation (AF), a condition in which the heart beats too quickly, could need a pacemaker. ![]() In many cases, a pacemaker may speed up a heartbeat that is too slow (bradycardia) or one that alternates between fast and slow. Pacemakers are typically given to patients who have an arrhythmia (an irregular or abnormal heartbeat). You can learn more about this surgical procedure below. “Pacemaker implantation” is the surgical procedure in which the pacemaker is inserted into the patient’s body. The device is implanted just beneath the skin, near the heart, in a minor surgical procedure. What is a pacemaker? What is pacemaker implantation?Ī pacemaker is a small implantable device that monitors and regulates heart rate.
