Long-term Ambulatory Monitors
There are two broad classifications for cardiac event monitors: manual (or dumb) and automatic. Automatic ECG event monitors such have the ability to monitor the patient's ECG and make recordings of abnormal events without requiring patient intervention. Manual ECG event recorders require patient to be symptomatic and to activate the device to record an event; this makes these devices useless whilst, for example, the patient is sleeping.
An example is the transtelephonic cardiac event monitor. This monitor contacts ECG technicians, via telephone, on a regular basis transmitting ECG rhythms for ongoing monitoring. The transtelephonic cardiac event monitor can normally store approximately five "cardiac events" usually lasting 30–60 seconds.

Famous quotes containing the words long-term and/or monitors:
“The strongest and most effective [force] in guaranteeing the long-term maintenance of ... power is not violence in all the forms deployed by the dominant to control the dominated, but consent in all the forms in which the dominated acquiesce in their own domination.”
—Maurice Godelier (b. 1934)
“To anybody who can hold the Present at its worth without being inappreciative of the Past, it may be forgiven, if to such an one the solitary old hulk at Portsmouth, Nelson’s Victory, seems to float there, not alone as the decaying monument of a fame incorruptible, but also as a poetic approach, softened by its picturesqueness, to the Monitors and yet mightier hulls of the European ironclads.”
—Herman Melville (1819–1891)
