Electrocardiographs, Ambulatory, Loop-Recording, External
Definition : Ambulatory electrocardiographs designed for external recording of the variations of the electric potential caused by the electrical activity of the heart muscle only for a pre-established, relatively short period of time (typically less than one hour), and then record again on the same memory erasing the previous information. (i.e., loop recording). These devices typically consist of an electronic storage device attached to the patient (e.g., on a belt) and two or more electrodes placed on the chest and connected to the recorder. The recorder measures and stores information continuously, thus detecting and recording arrhythmia episodes lasting several minutes; the recording period may be increased a few minutes after patient activation. The information can be transferred to a patient-operated device that allows the telemetric communication of the stored data to the physician's office, usually through standard telephone lines. A programmer-tester device used to set up the recorders at the time of setup and to save or retrieve the recorder information later is also available. The recorders are mainly used in patients who have syncope or presyncope events and/or cardiac arrhythmia. Loop recording ECGs are not intended for a real-time assessment of the electrocardiogram or other cardiac conditions.
