Exercise-induced bronchospasm
|
|
Exercise-induced bronchospasmAlso 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.
RELATED TERMS--------------------------------------
Asthma
Asthma is a chronic, inflammatory lung disease characterized by recurrent breathing problems. People with asthma have acute episodes or when the air passages in their lungs get narrower, and breathing becomes more difficult. Sometimes episodes of asthma are triggered by allergens, although infection, exercise, cold air and other factors are also important triggers.
Affect
This word is used to described observable behavior that represents the expression of a subjectively experienced feeling state (emotion). Common examples of affect are sadness, fear, joy, and anger. The normal range of expressed affect varies considerably between different cultures and even within the same culture. Types of affect include: euthymic, irritable, constricted; blunted; flat; inappropriate, and labile.

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.
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.
Exercise treadmill test
A test (sometimes simply called a treadmill test or exercise 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.
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
Exocrine gland
A gland that secretes a substance out through a duct. The exocrine glands include the salivary glands, sweat glands and glands within the gastrointestinal tract. The exocrine glands are the "glands of external secretion."
Exogenous DNA
DNA originating outside an organism.
Exonuclease
An enzyme that cleaves nucleotide bases sequentially from the free ends of a nucleic acid (DNA or RNA).
Exopeptidase
An enzyme that catalyzes the cleavage of the terminal (last) or next-to-last peptide bond from a polypeptide or protein, releasing a single amino acid or dipeptide. By contrast, an endopeptidase catalyzes the cleavage of then internal peptide bonds within a polypeptide or protein.
Expectorant
A medication that helps bring up mucus and other material from the lungs, bronchi, and trachea. An example of as expectorant is guaifenesin which promotes drainage of mucus from the lungs by thinning the mucus and also lubricates the irritated respiratory tract. Sometimes the term "expectorant" is incorrectly extended to any cough medicine.
