Ambulatory electrocardiogram (Holter)

The Holter electrocardiogram or ambulatory electrocardiogram is a diagnostic test that allows, during 24 hours, the continuous recording of the heart’s electrical activity. The recording is carried out by means of a magnetic tape that the patient wears connected to different points in the chest area while he/she goes about his/her daily life. The analysis of the results is performed with a fast-paced system that allows analysis, in about twenty minutes, of the 24-hour tracing of the heart’s activity, and automatic recording of the abnormalities obtained, different types of arrhythmias, conduction blockages, etc. Generally, this technique is used when the possibility of arrhythmias or blockages that do not appear on a conventional electrocardiographic tracing is suspected.
