2Ĭardiac rhythm monitoring has an established diagnostic and prognostic role in different circumstances: syncope, palpitations and monitoring of patients with known or suspected episodes of atrial fibrillation(AF), e.g. 2 In other circumstances the detection of atrial or ventricular arrhythmias may alert the cardiologist, even if they occur asymptomatically, thus prompting a specific therapeutic decision such as starting antiarrhythmic or anticoagulant drugs or implanting a pacemaker or a cardioverter defibrillator. When interpreting the results of the ECG, the cardiologist has to determine whether symptoms reported by the patient could be linked to significant disturbances in heart rhythm. 1,2 This need for a prolonged ECG monitoring has been addressed by event recorders, which can monitor patients for up to 3 years, storing the ECG obtained a few minutes before and after the onset of an arrhythmia in its memory and transmitting data to the cardiac unit. 1 Extending the time of ECG registration will increase the diagnostic yield of Holter monitoring, especially for those rhythm disturbances that are infrequent but recurrent. 1 The most common monitoring systems allow the continuous registration of three or more leads for 24–48 hours newer Holter monitors allow continuous electrocardiogram (ECG) registration for 2 weeks. We’ll help you get to the bottom of your heart issues and live a happier, healthier life.Since the 1960s, Holter monitoring has been a cornerstone for diagnosing suspected arrhythmias in patients of all ages. If you’ve been having trouble with fainting, dizziness, or other symptoms that may indicate arrhythmia, call Oklahoma Heart Hospital and set up an appointment. Your doctor may suggest implanting a pacemaker or other device, or there may be medications you can take to control the arrhythmia. If your ILR captures an arrhythmia, there are a variety of treatment options that may be available. What happens after a loop recorder is implanted? With their longer-term recording ability, ILRs allow for more intermittent problems to be diagnosed effectively. In those cases, a doctor may recommend the implantation of an ILR. The basic tests like ECG, tilt-table, or a Holter monitor may not show anything conclusive. For patients with intermittent fainting episodes, there could be many different causes that are difficult to identify. ILRs are often used to get more conclusive results when other forms of testing fail. An ILR can start recording your heart rhythm automatically based on certain parameters, but a user can also trigger it manually if they feel symptoms. Unlike a Holter monitor or other monitoring devices, there are no wires or other external accessories, so you don’t have to worry about getting wet or not being able to keep up regular activity levels. It’s smaller than a key or a thumb drive, and it shouldn’t impede movement or daily life in any way once the incision heals. The procedure to implant a loop recorder involves a local anesthetic and a small incision to place the device just under the skin of the chest. It has a solid state memory and a 15- to 18-month battery life. Unlike a Holter monitor, though, it’s not designed to just work for a few days-it is implanted under your skin and can work for years. What is an implantable loop recorder?Īn implantable loop recorder, like a Holter monitor, is a device that records information about heart rhythms. If other tests like an in-office ECG and a Holter monitor haven’t identified a cause for your heart rhythm issues and your symptoms persist, a loop recorder may be the next step. If you’ve been dealing with fainting spells, dizziness, or other symptoms that may come from a heart arrhythmia, you might need an implantable loop recorder.
