Stress
Acceleration of heart and lung action, paling or flushing, or alternating between both, inhibition of stomach and upper-intestinal action to the point where digestion slows down or stops, the general effect on the sphincters of the body, constriction of blood vessels in many parts of the body, liberation of nutrients (particularly fat and glucose) for muscular action, dilation of blood vessels for muscles, inhibition of the lacrimal gland (responsible for tear production) and salivation, dilation of pupil (mydriasis), relaxation of bladder, inhibition of erection, auditory exclusion (loss of hearing), tunnel vision (loss of peripheral vision), disinhibition of spinal reflexes, and Shaking
Stress can cause or influence the course of many medical conditions including psychological conditions such as depression and anxiety. Medical problems can include poor healing, irritable bowel syndrome, high blood pressure, poorly controlled diabetes and many other conditions. Stress management is recognized as an effective treatment modality to include pharmacologic and non-pharmacologic components.

- Stress echocardiography
A supplement to the routine exercise cardiac stress test. During stress echocardiography, the sound waves of ultrasound are used to produce images of the heart at rest and at the peak of exercise. In a heart with normal blood supply, all segments of the left ventricle (the major pumping chamber of the heart) exhibit enhanced […]
- Stress exercise thallium scan
an exercise part and a rest part. The patient has an IV (intravenous) line placed in the arm, EKG patches are applied to chest and connected to an EKG machine to monitor the heart. Then the patient exercises as hard as possible on the treadmill to give information about how well the heart functions with […]
- Stress fracture
A fracture caused by repetitive stress, as may occur in sports, strenuous exercise, or heavy physical labor. Stress fractures are especially common in the metatarsal bones of foot, particularly in runners. Osteoporosis increases the possibility of stress fractures. Treatment is by rest, disuse, and sometimes splinting or casting to prevent reinjury during healing.
- Stress test, pharmacologic
There are a diversity of pharmacologic stress tests. Here this refers specifically to a pharmacologic cardiac stress test in which certain medications are administered that stimulate the heart to mimic the physiologic effects of exercise. One of the medications used in a pharmacologic stress test is dobutamine, which is similar to adrenaline. Dobutamine is carefully […]
- Stress test, physiologic
Although there can be a diversity of physiologic stress tests, this refers here to a physiologic cardiac stress test in which certain medications are administered that stimulate the heart to mimic the physiologic effects of exercise. One of these medications is dobutamine, which is similar to adrenaline. Dobutamine is carefully administered to gradually increase the […]
