Ambulatory Electrocardiography Device

Ambulatory EKG

holter monitor

Named after its inventor, Dr. Norman J. Holter, is a portable device for continuously monitoring the electrical activity of the heart for 24 hours or more. Its extended recording period is useful for observing occasional cardiac arrhythmias that would be otherwise difficult to identify in a shorter period of time.

 

Much like standard electrocardiography ( EKG ), the Holter monitor records electrical signals from the heart via a series of electrodes attached to the chest. The number and position of electrodes varies by model, but most Holter monitors employ from three to seven. Typical devices use a standard C60 or C90 audio cassette run at a very slow speed to record the data. More modern units record onto digital flash memory devices. The data is uploaded into a computer which then automatically analyses the input, counting ECG complexes, calculating summary statistics such as average heart rate, minimum and maximum heart rate, and finding candidate areas in the recording worthy of further study by the technician.

 

The recording device of a Holter monitor is worn on a strap at your waist or over your shoulder. The electrical signals of your heart are picked up by two small metal pads (electrodes) attached to your chest, and these are connected to the recorder by wires.

 

Holter monitoring provides a continuous 24- to 72-hour record of the electrical signals from your heart. While wearing the Holter monitor, you will also be asked to keep a diary of all your activities and symptoms. After the monitoring period, your health professional will compare the timing of your activities and symptoms with the recorded heart pattern.
