• Other cardiac monitoring devices, such as an ECG or a Holter monitor, may not be able to answer questions about your heart that an implantable loop recorder can.
• The information collected by an ECG or a conventional Holter monitor is just for the duration of the test. Because some heart rhythm abnormalities occur infrequently, they can be missed.
• An implantable loop recorder can monitor your heart impulses for a long time it will record your heart's function or abnormalities during an event. 
• Your doctor can make a specific diagnosis and prepare a treatment plan by using the information collected through a loop recorder.
• Long-term cardiac monitoring using an implantable loop recorder revealed heart rhythm problems that caused stroke better than 24-hour Holter monitor. Doctors have used the results to help prevent certain strokes when administering blood-thinning drugs.
