1. Pertaining to, or capable of walking: "It was an ambulatory exploration of the city."
2. Adapted for walking, as the limbs of many animals.
3. Moving around or from place to place; not stationary.
4. Not confined to bed; able or strong enough to walk: "He was an ambulatory patient who could go home instead of having to stay in a hospital bed."

"An ambulatory health service is for people who are not required to be hospitalized because they are not physically handicapped and so they are able to walk in a normal way."

5. Serving patients who are able to walk: "The health clinic offered an ambulatory care center."
6. In law, not fixed; alterable or revocable: "He left an ambulatory will."

1. An aisle surrounding the end of the choir or chancel of a church.
2. The covered walk of a cloister: "The visitors were walking around in the ambulatory of the historical cloister."

The administration of anesthesia when the patient is admitted and discharged on the same day of a surgical procedure.

Aimless wandering or moving around: "The ambulatory automatism of a person includes the performance of mechanical acts without any conscious awareness of doing such movements."

"During ambulatory automatisms, epileptic patients walk around and are able to carry out some functions without being clearly conscious of either themselves or their surroundings."

Monitoring of a patient that allows the blood pressure to be recorded at regular intervals under normal living and working conditions and is useful to determine to what degree a patient's blood pressure falls at night compared to daytime values: "Ambulatory blood pressure monitoring consists of prolonged blood pressure readings that are made while a patient does normal daily activities that will allow quantitative analyses of high blood pressure loads over different times and which can help distinguish between types of hypertensions; as well as, assess the effectiveness of antihypertensive therapies."

A reference to health services that are provided on an outpatient basis: "Those who visit a hospital, or another healthcare facility, and then go back home after treatment on the same day, are identified as being ambulatory care patients."

A form of schizophrenia or any of several psychotic disorders characterized by distortions of reality, usually of the simple but also of the schizoaffective type (symptoms of both schizophrenia and mood disorders): "The person so afflicted with ambulatory schizophrenia manages for the most part to avoid being institutionalized."

Medical facilities that are designed and equipped to handle surgery, pain management, and specific diagnostic procedures which do not require overnight hospitalization: "Patients who are in relatively good health may choose to receive treatments at ambulatory surgery centers instead of having to stay over night in a room and they will be treated by health professionals just as they would in a conventional surgery department."

An essential tool in the diagnostic evaluation of patients with cardiac arrhythmias.

Recent advances in digital Holter technology have improved the quality of the ECG signals and new dedicated algorithms have expanded the clinical application of software-based AECG analysis systems.

Holter monitoring is used to help determine whether someone has an otherwise undetected heart disease; such as, an abnormal heart rhythm (cardiac arrhythmia), or inadequate blood flow through the heart.

Specifically, it can detect abnormal electrical activity in the heart which may occur randomly or only under certain circumstances; such as, during sleep or periods of physical activity or stress, which may or may not be picked up by standard, short-term electrocardiography performed in a doctor's office.

There are no known risks associated with Holter monitoring. The main complaint that people have with Holter monitoring is that the monitor may be cumbersome and interfere with certain activities, especially sleeping. Bathing and showering are not allowed during the monitoring period.

The Holter monitoring device is named after Norman J. Holter, D.Sc., a U.S. physicist who is known as "the father" of ambulatory ECG monitoring and recording signals from leads on the chest of a patient and recording them onto magnetic tape for later analysis.

The Holter recorder is quite common and many people with suspected heart problems are instructed to "wear" one for 24 hours during which time the electrodes that are attached to the chest pick up the ECG signals.

The signals are recorded on a cassette tape that runs slowly for a 24 hour recording, then the tape is quickly analyzed by a machine which stops when it detects any abnormalities in the recording.

The electrocardiographic technician, who controls the playback machine, makes notes to report back to a physician.
