Exercise ECG
Exercise ECG Monitoring the electrical activity of the heart muscles while the heart is under stress, usually induced by the subject walking on a treadmill.
RELATED TERMS--------------------------------------
Monitoring
The act of overseeing the progress of a clinical trial, and of ensuring that it is conducted, recorded, and reported in accordance with the protocol, standard operating procedures (S0Ps), good clinical practice (GCP), and the applicable regulatory requirement(s).
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Stress
Mental or physical tension that results from physical, emotional, or chemical causes.
SIMILAR TERMS--------------------------------------
Exercise Stress Test
A test used to provide information about how the heart responds to stress. It usually involves walking on a treadmill or pedaling a stationary bike at increasing levels of difficulty, while the electrocardiogram, heart rate and blood pressure are monitored. When one is not able to do activity, medications may be used to "stress" the heart. This is called a pharmacological stress test.
Exercise test
A test (sometimes called the treadmill test or exercise treadmill test) in which a continuous electrocardiogram (ECG or EKG) recording of the heart is made as the patient performs increasing levels of exercise on the treadmill which is tilted to produce the effect of going up a small hill. The patient can stop the test at any time, if necessary. Afterwards the patient has heart and blood pressure checked. There is very little risk in taking the test in healthy persons -- no more than if a person walks fast or jogs up a big hill. Medical professionals should be present in case something unusual happens during the test. The exercise test screens for the presence of narrowed coronary arteries that can limit the supply of oxygenated blood to the heart muscle during exercise. The test also detects abnormal heart rhythms (arrhythmias).
Exercise treadmill
Exercise on a treadmill, a machine with a moving strip on which one walks without moving forward. A treadmill was originally a wide wheel turned by the weight of people climbing on steps around its edge, used in the past to provide power for machines or as a punishment in prisons.

The patient can stop the test at any time, if necessary. Afterwards the patient has heart and blood pressure checked.
Exercise, isometric
Exercise involving muscular contractions without movement of the involved parts of the body. Isometric exercise is one method of muscular exercise. In contrast, isotonic exercise occurs when a contracting muscle shortens against a constant load, as when lifting a weight.
Exercise, isotonic
Exercise when a contracting muscle shortens against a constant load, as when lifting a weight. Isometric exercise is one method of muscular exercise. In contrast, isotonic exercise is when muscular contractions occur without movement of the involved parts of the body.
Exercise, passive
Movement of the body, usually of the limbs, without effort by the patient. The patient is passive.
Exercise-induced asthma
Asthma that is "triggered" by vigorous physical activity. Exercise-induced asthma tends particularly to affect children and young adults (because of their high level of physical activity) but can occur at any age.
Exercise-induced bronchospasm
Also called exercise- induced asthma, this is asthma that is triggered by vigorous physical activity. Exercise-induced asthma tends particularly to affect children and young adults (because of their high level of physical activity) but can occur at any age.

Exacerbate
Cause something to increase in severity. To make more intense, irritate.
Exanthem
Skin rash.
Excise
To remove by cutting.
Exocrine glands
Glands that secrete chemicals externally, either through a tube or duct.
ECG (electrocardiograph or cardiograph)
A tracing of the electrical activities of the heart muscles by means of an electrocardiogram, which is connected to sensors placed on the body.ÿ This procedure is used to detect and monitor suspected heart disorders.
Exercise ECG
EEG (electroencephalograph)
A tracing of the electrical activity of the brain by means of an electroencephalograph connected to the sensors placed on the scalp.ÿ In this way, certain conditions such as epilepsy, brain tumours and other diseases or injuries to the brain can be diagnosed.
EMG (electromyograph)
The recording, by means of fine needles inserted into muscles, of electrical currents generated into the muscles.ÿ This is used in the diagnosis of muscle and nerve disorders.
Embryonic
Undeveloped, related to the embryo.
Encapsulated
Refers to a tumor that is wholly confined to a specific area, surrounded by a capsule. Localized.
Evoked potentials
The use of electrodes to measure the electrical activity of nerves. May be used as a guide during surgical removal of tumors growing around important nerves.
