Discussion on Holter monitoring.
Holter monitoring is continuous monitoring and recording of two or more surface electrocardiographic leads in a solid state memory.
Recordings on magnetic audio cassettes are now obsolete and the recorders have solid state flash memory so that the device size has also come done remarkably.
The devices can record 24 to 72 hours of data from the electrocardiographic leads usually attached on the subject’s chest with disposable silver - silver chloride electrodes.
After completion of recording, the recording device is removed and the data downloaded into the Holter analyser, usually a personal computer with appropriate hard ware card and software installed.
