The device tells your healthcare team how the heart is beating while you do your daily activities.<\/p>\n<p>Other names for this device are:<\/p>\n<ul>\n<li>Implantable event recorder.<\/li>\n<li>Cardiac event recorder.<\/li>\n<\/ul>\n<p>The small device is placed just under the skin of the chest during a minor surgery.<\/p>\n<p>Your healthcare professional may recommend an implantable loop recorder if you have:<\/p>\n<ul>\n<li>An irregular heartbeat, called an arrhythmia.<\/li>\n<li>An unexplained stroke.<\/li>\n<li>Unexplained fainting.<\/li>\n<\/ul>\n<p>An implantable loop recorder can see changes in the heartbeat that other heart-recording devices may miss. For example, it may find irregular heartbeats that are brief or that only happen once in a while.<\/p>\n<p>If you have been fainting, your healthcare professional may recommend this device to see if a heart condition is the cause. Information from the recorder can help your healthcare team make a diagnosis and plan treatment.<\/p>\n<p>An implantable loop recorder also may be recommended if you&#8217;re at high risk of stroke. Some irregular heartbeats, such as atrial fibrillation, increase the risk of stroke.<\/p>\n<p>An implantable loop recorder is placed during a minor surgery. All surgery has risks. But complications of implantable loop recorder placement are uncommon.<\/p>\n<p>Possible risks may include:<\/p>\n<ul>\n<li>Bleeding.<\/li>\n<li>Infection.<\/li>\n<\/ul>\n<p>An implantable loop recorder is considered safe for use during magnetic resonance imaging (MRI). But always tell your healthcare team that you have one before you schedule an MRI.<\/p>\n<p>An implantable loop recorder might be spotted by metal detectors, for example, at an airport. Your healthcare team can give you a device identification card to carry with you for such situations.<\/p>\n<h3>Before<\/h3>\n<p>There&#8217;s no special preparation for the placement of an implantable loop recorder.<\/p>\n<h3>During<\/h3>\n<p>An implantable loop recorder is placed under the skin on the chest. The minor surgery is usually done in a medical office or medical center.<\/p>\n<p>You are awake for the procedure. You may get medicine to help you relax. A member of your healthcare team numbs your chest area, which means you won&#8217;t feel anything. The doctor makes a tiny cut in the chest and inserts the device. The wound is closed. The device stays in place for up to three years.<\/p>\n<h3>After<\/h3>\n<p>After the device is placed, watch the skin for symptoms of infection. This includes swelling or a change in skin color. You may be told not to do some activities until the wound heals.<\/p>\n<p>You get a device called a transmitter to place beside your bed. It automatically sends information from the recorder to your healthcare professional while you sleep. You also can push a button to send the information immediately if you have symptoms. Your healthcare team may ask you to keep a notebook of any symptoms.<\/p>\n<p>You usually need health checkups once or twice a year while the device is in place.<\/p>\n<p>Information from the recorder goes to your healthcare team. Your healthcare team talks with you about the results. If the device finds a concerning change in your heartbeat, your healthcare team may tell you to go to the hospital.<\/p>\n<p>An implantable loop recorder doesn&#8217;t interfere with your daily activities. It has no patches or wires. You don&#8217;t have to worry about getting the device wet while bathing or swimming.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Learn how this implanted device records your heartbeat and know when you might need one.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","tags":[1686,1687,1682],"class_list":["post-52930","mayo","type-mayo","status-publish","hentry","tag-anatomical-structure","tag-medical-procedure","tag-person-group-concept","content_type-tests-procedures"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
