Cardiac Stress Test
A cardiac stress test (also referred to as a cardiac diagnostic test, cardiopulmonary exercise test, or abbreviated CPX test) is a cardiological test that measures the heart's ability to respond to external stress in a controlled clinical environment. The stress response is induced by exercise or by intravenous pharmacological stimulation. Cardiac stress tests compare the coronary circulation while the patient is at rest with the same patient's circulation during maximum cardiac exertion, showing any abnormal blood flow to the myocardium (heart muscle tissue). The results can be interpreted as a reflection on the general physical condition of the test patient. This test can be used to diagnose coronary artery disease (also known as ischemic heart disease) and assess patient prognosis after a myocardial infarction (heart attack). Exercise-induced stressors are most commonly either exercise on a treadmill or pedalling a stationary exercise bicycle ergometer. The level of stress ...

Stress Testing
Stress testing (sometimes called torture testing) is a form of deliberately intense or thorough testing used to determine the stability of a given system, critical infrastructure or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results. Reasons can include: * to determine breaking points or safe usage limits * to confirm mathematical model is accurate enough in predicting breaking points or safe usage limits * to confirm intended specifications are being met * to determine modes of failure (how exactly a system fails) * to test stable operation of a part or system outside standard usage Reliability engineers often test items under expected stress or even under accelerated stress in order to determine the operating life of the item or to determine modes of failure. The term "stress" may have a more specific meaning in certain industries, such as material sciences, and therefore stress testing may sometimes have ...

Stress Test (hardware)
A stress test (sometimes called a torture test) of hardware is a form of deliberately intense and thorough testing used to determine the stability of a given system or entity. It involves testing ''beyond normal operational capacity'', often to a breaking point, in order to observe the results. Reasons can include: to determine breaking points and safe usage limits; to confirm that the intended specifications are being met; to determine modes of failure (how exactly a system may fail), and to test stable operation of a part or system outside standard usage. Reliability engineers often test items under expected stress or even under accelerated stress in order to determine the operating life of the item or to determine modes of failure. The term ''stress test'' as it relates to hardware (including electronics, physical devices, nuclear power plants, etc.) is likely to have different refined meanings in specific contexts. One example is in materials, ''see Fatigue (material)''. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress Testing (software)
Stress testing is a software testing activity that determines the robustness of software by testing beyond the limits of normal operation. Stress testing is particularly important for "mission critical" software, but is used for all types of software. Stress tests commonly put a greater emphasis on robustness, availability, and error handling under a heavy load, than on what would be considered correct behavior under normal circumstances. Field experience Failures may be related to: *characteristics of non-production like environments, e.g. small test databases *complete lack of load or stress testing Rationale Reasons for stress testing include: * The software being tested is "mission critical", that is, failure of the software (such as a crash) would have disastrous consequences. * The amount of time and resources dedicated to testing is usually not sufficient, with traditional testing methods, to test all of the situations in which the software will be used when it is release ...

Stress Test (financial)
A stress test, in financial terminology, is an analysis or simulation designed to determine the ability of a given financial instrument or financial institution to deal with an economic crisis. Instead of doing financial projection on a "best estimate" basis, a company or its regulators may do stress testing where they look at how robust a financial instrument is in certain crashes, a form of scenario analysis. They may test the instrument under, for example, the following stresses: * What happens if unemployment rate rises to v% in a specific year? * What happens if equity markets crash by more than w% this year? * What happens if GDP falls by x% in a given year? * What happens if interest rates go up by at least y%? * What if half the instruments in the portfolio terminate their contracts in the fifth year? * What happens if oil prices rise by z%? * What happens if there is a polar vortex event in a particular region? This type of analysis has become increasingly widespread, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress Test (book)
''Stress Test: Reflections on Financial Crises'' is a 2014 memoir by former United States Secretary of the Treasury Timothy Geithner, written as an account of the effort to save the United States economy from collapsing in the wake of the 2008 financial crisis. Journalist Michael Grunwald is credited as Geithner's collaborator for the writing. It was listed for five consecutive weeks on ''The New York Times'' Non-Fiction Bestseller list upon its release in May 2014. ''Stress Test'' details how "The financial crisis exposed our system of consumer protection as a dysfunctional mess, leaving ordinary Americans way too vulnerable to fraud and other malfeasance", and notes that "Many borrowers, especially in subprime markets, bit off more than they could chew because they didn’t understand the absurdly complex and opaque terms of their financial arrangements, or were actively channeled into the riskiest deals."

Contraction Stress Test
A contraction stress test (CST) is performed near the end of pregnancy (34 weeks' gestation) to determine how well the fetus will cope with the contractions of childbirth. The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph. A CST is one type of antenatal fetal surveillance technique. During uterine contractions, fetal oxygenation is worsened. Late decelerations in fetal heart rate occurring during uterine contractions are associated with increased fetal death rate, growth retardation and neonatal depression. This test assesses fetal heart rate in response to uterine contractions via electronic fetal monitoring. Uterine activity is monitored by tocodynamometer. Medical uses The CST is used for its high negative predictive value. A negative result is highly predictive of fetal wellbeing and tolerance of labor. The test has a poor positive predictive value with false-positive results in as many as 30% of cases. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voice Stress Analysis
Voice stress analysis (VSA) and computer voice stress analysis (CVSA) are collectively a pseudoscience, pseudoscientific technology that aims to infer deception from stress measured in the voice. The CVSA records the human voice using a microphone, and the technology is based on the tenet that the non-verbal, low-frequency content of the voice conveys information about the physiological and psychological state of the speaker. Typically utilized in investigative settings, the technology aims to differentiate between stressed and non-stressed outputs in response to stimuli (e.g., questions posed), with high stress seen as an indication of deception. Scientific findings The use of voice stress analysis (VSA) for the detection of deception is controversial. Discussions about the application of VSA have focused on whether this technology can indeed reliably detect stress, and, if so, whether deception can be inferred from this stress. Critics have argued that—even if stress could relia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highly Accelerated Life Test
A highly accelerated life test (HALT) is a stress testing methodology for enhancing product reliability in which prototypes are stressed to a much higher degree than expected from actual use in order to identify weaknesses in the design or manufacture of the product. Manufacturing and research and development organizations in the electronics, computer, medical, and military industries use HALT to improve product reliability. HALT can be effectively used multiple times over a product's life time. During product development, it can find design weakness earlier in the product lifecycle when changes are much less costly to make. By finding weaknesses and making changes early, HALT can lower product development costs and compress time to market. When HALT is used at the time a product is being introduced into the market, it can expose problems caused by new manufacturing processes. When used after a product has been introduced into the market, HALT can be used to audit product reliabil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
