. Jump to navigation Jump to search. In medicine, a Holter monitor (often simply Holter) is a type of ambulatory electrocardiography device, a portable device for cardiac monitoring (the monitoring of the electrical activity of the cardiovascular system) for at least 24 to 48 hours (often for two weeks at a time).Inventor: 

What is a holter monitor?

The Holter monitor was released for commercial production in 1962. When used to study the heart, much like standard electrocardiography, the Holter monitor records electrical signals from the heart via a series of electrodes attached to the chest.

Can a holter monitor detect heart rhythm?

Over that time, the Holter monitor may be able to detect irregularities in your heart rhythm that an electrocardiogram couldn’t detect. Your doctor may also order a Holter monitor if you have a heart condition that increases your risk of an abnormal heart rhythm.

What is a cardiac event monitor?

For patients having more transient symptoms, a cardiac event monitor which can be worn for a month or more can be used. The Holter monitor was developed at the Holter Research Laboratory in Helena Montana by experimental physicists Norman J. Holter and Bill Glasscock, who started work on radio telemetry in 1949.

What is Holter’s use for?

The Holter’s most common use is for monitoring ECG heart activity (electrocardiography or ECG). Its extended recording period is sometimes useful for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period.

What purpose does a holter monitor serve?

A Holter monitor is a medical device that can help to diagnose heart problems , such as arrhythmias . A technician will attach electrodes to a person’s chest, and the person will wear the monitor

What does a holter monitor look like?

The average dimensions of today’s Holter monitors are about 110x70x30 mm but some are only 61x46x20 mm and weigh 99 g. Most of the devices operate with two AA batteries. In case the batteries are depleted, some Holters allow their replacement even during monitoring.

What to expect during Holter monitoring?

What to Expect During a Holter Monitor Test. Your Holter monitor test will begin in your doctor’s office. It is best to wear loose-fitting clothing during your test, allowing the electrodes to stay in place. A nurse or technician will clean your skin, then attach electrodes to your chest.

How is a holter monitor similar to an electrocardiogram?

A Holter monitor is similar to an ECG (electrocardiogram). However, a standard ECG only records the heartbeat for a few seconds. It won’t detect heart rhythm problems which don’t occur during the test. Some people have heart rhythm problems that occur only during certain activities, such as sleeping or physical exertion.
