Each Holter system has hardware (called monitor or recorder) for recording the signal, and software for review and analysis of the record. There may be a "patient button" on the front that the patient can press at specific instants such as feeling/being sick, going to bed, taking pills, marking an event of symptoms which is then documented in the symptoms diary, etc.; this records a mark that ...
Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm. Cardiac monitoring is usually carried out using electrocardiography , which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram ...
The Holter contains a removable Portable Computer Memory Card International Adapter (PCMCIA) card that allows the data to be stored, downloaded to a personal computer, and downlinked. The Human Research Facility Holter Monitor (Holter) measures and records the electrical activity of a crew member's heart. The Holter is a battery-powered digital ...

Monitoring can be classified by the target of interest, including: Cardiac monitoring, which generally refers to continuous electrocardiography with assessment of the patient's condition relative to their cardiac rhythm. A small monitor worn by an ambulatory patient for this purpose is known as a Holter monitor.
An implantable loop recorder (ILR), also known as an insertable cardiac monitor (ICM), is a small device that is implanted under the skin of the chest for cardiac monitoring, to record the heart's electrical activity for an extended period.
Early models consisted of a monitoring box with a set of electrode leads which attached to the chest. The first wireless EKG heart rate monitor was invented in 1977 by Polar Electro as a training aid for the Finnish National Cross Country Ski team. As "intensity training" became a popular concept in athletic circles in the mid-80s, retail sales ...
Before the development of the Bruce protocol there was no safe, standardized protocol that could be used to monitor cardiac function in exercising patients. Master's two-step test [7] was often used, but it was too strenuous for many patients, and inadequate for the assessment of respiratory and circulatory function during varying amounts of ...
