Holter monitor

Syllabification: (Holt·er mon·i·tor)
Pronunciation: /ˈhōltər/

Definition of Holter monitor

noun

  • a portable device that records the rhythm of the heart continuously, typically for 24-48 hours, by means of electrodes attached to the chest.

Origin:

1950s: named after Norman J. Holter (1914–83), the American biophysicist who invented it

When a patient is fitted with a Holter monitor, the recording device may be on a strap that goes around the neck or over the shoulder. This procedure is so suggestive of wearing a halter that it is not surprising that many people, including some healthcare professionals, believe they are correct in calling the device a halter monitor. In fact, the true name has nothing to do with the way the device is worn, but refers only to the man who invented it: Norman J. Holter. Even though the pronunciations of Holter and halter differ, the mistaken identity is persistent.
