An event recorder which is also known as a loop recorder, is a small device that is implanted under the skin and used in the diagnosis of cardiac arrhythmias. Event recorders fulfill the role of a miniature ambulatory ECG device, and are mainly used to treat patients who experience recurrent syncope (fainting spells) of unknown origin.
The device is implanted under local anesthesia. It is implanted through an incision 3cm in length, and positioned under the skin but above the layer of muscle inside the chest. The event monitor effectively functions as a miniature ambulatory ECG device by continuously recording the hearts electrical activity. Recording starts as soon as a pre-defined heart rate is reached. If the patient experiences symptoms, recording can also be started manually (patient-activated).
Cardiology research Journals like Clinical Cardiology and Cardiovascular Medicine (CCCM) provides a global open access platform to put forth the ongoing research, reviews articles related to all the tests related to heart including the heart devices.
