| stress test | Any cardiac challenge, physical, pharmacologic, or mental delivered under monitored conditions. Most commonly this is exercise, the most common monitor being electrocardiography although any other graphic technique, including cardiac catheterization, may be applied. (05 Mar 2000) |
|---|---|
| stress ulcers | An ulcer of the duodenum in a patient with extensive superficial burns, intracranial lesions, or severe bodily injury. Synonym: stress ulcers. (05 Mar 2000) |
| stress urinary incontinence | Leakage of urine as a result of coughing, straining, or some sudden voluntary movement, due to weakness of the fascia muscles and at the neck of the bladder. Synonym: urinary exertional incontinence. (05 Mar 2000) |
| dental stress analysis | The description and measurement of the various factors that produce physical stress upon dental restorations, prostheses, or appliances, materials associated with them, or the natural oral structures. (12 Dec 1998) |
| oxidative stress | A highly oxidized environment within cells that is thought to promote HIV replication because cells are forced into a highly activated state due to loss of control of their regulatory systems. (09 Oct 1997) |
| tensile stress | A stress acting on a body per unit cross-sectional area so as to elongate the body. (05 Mar 2000) |
| thallium stress test | <cardiology, investigation> This test is used to assess coronary blood flow before and after a period of strenuous exercise. Thallium testing involves the introduction of a radioactive tracer into the bloodstream. The radioactive tracer is then measured with a special camera and a determination of coronary artery blood flow can be made. (27 Sep 1997) |
| yield stress | The critical stress that must be applied to a material before it begins to flow, as in a Bingham plastic. (05 Mar 2000) |
| urinary incontinence, stress | The involuntary discharge of urine as a result of anatomic displacement which exerts an opening pull on the bladder orifice. It often occurs during coughing or other forceful stresses. (12 Dec 1998) |
| fractures, stress | Fractures due to the strain caused by repetitive exercise. They are thought to arise from a combination of muscle fatigue and bone failure, and occur in situations where bone remodeling predominates over repair. The classical stress fracture is the march fracture of military personnel, in which the metatarsal undergoes repeated stress during marching. The most common sites of stress fractures are the metatarsus, fibula, tibia, and femoral neck. (12 Dec 1998) |
| life stress | Events or experiences that produce severe strain, e.g., failure on the job, marital separation, loss of a love object. (05 Mar 2000) |
| arrhythmias, atrial | Abnormal heart rhythm due to electrical disturbances in the atria (the upper chambers of the heart) or the AV node relay station , leading to fast heart beats. Examples of atrial arrhythmias includes atrial fibrillation, atrial flutter, and paroxysmal atrial tachycardia (PAT). (12 Dec 1998) |
| atrial | <anatomy> Pertaining to an atrium. (16 Dec 1997) |
| atrial appendage | The small projection from each atrium hanging over like a small ear, more marked on the left, with a small cavity of its own. (05 Mar 2000) |
| atrial arrhythmias | See Arrhythmias, atrial. (12 Dec 1998) |
