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 ...
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 ...
There are many different types of cardiac monitors. In personal use, the Holter monitor is an external monitor which uses wires with patches that attach to the skin to continuously measure and record heart activity for 1–2 days. [5] An Event Recorder can be worn on the body for up to 30 days. [6]

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.
A small monitor worn by an ambulatory patient for this purpose is known as a Holter monitor. Cardiac monitoring can also involve cardiac output monitoring via an invasive Swan-Ganz catheter . Hemodynamic monitoring , which monitors the blood pressure and blood flow within the circulatory system.
Portable devices have existed since the Holter monitor was introduced in 1962. Traditionally, these monitors have used electrodes with patches on the skin to record the ECG, but new devices can stick to the chest as a single patch without need for wires, developed by Zio (Zio XT), TZ Medical (Trident), Philips (BioTel) and BardyDx (CAM) among ...
Norman Jefferis "Jeff" Holter (February 1, 1914 – July 21, 1983) was an American biophysicist who invented the Holter monitor, a portable device for continuously monitoring the electrical activity of the heart for 24 hours or more. Holter donated the rights to his invention to medicine.
