Electrocardiographs, Ambulatory, Continuous

Definition : Ambulatory electrocardiographs (ECGs) designed for continuous recording of the variations of the electric potential caused by the electrical activity of the heart muscle, usually detected at the body surface typically from three to twelve leads simultaneously. The instrument usually records ECG signals automatically using an electronic storage device (tape recorders may be also used) worn by the patient in which the recording function is always active and includes detachable chest surface electrodes. The recorded signals are analyzed in a processor that includes dedicated software. Also available are ambulatory ECGs that analyze the signal at the time that it is recorded, typically using microprocessors (i.e., real-time recording), and recorders that make the analysis when processing the recorded signal (i.e., retrospective recorders). Continuous ambulatory electrocardiographs are usually worn by the patient for a period of 24 to 48 hours and are used to detect transient cardiac problems (e.g., variable heart rate, arrhythmia), after myocardial infarction, or other problems of possible cardiac origin (e.g., dizziness, palpitations). Continuous ambulatory ECGs are not intended for a real-time assessment of the electrocardiogram or other cardiac conditions.
