| operations research | A group of techniques developed to apply scientific methods and tools to solve the problems of decision making in complex organizations and systems. Operations research searches for optimal solutions in situations of conflicting goals and makes use of mathematical models from which solutions for actual problems may be derived. (12 Dec 1998) |

| electrophysiological studies | <investigation> A special study that involves the placement of electrodes inside the heart to map the electrical characteristics of the heart. This study is carried out in a specially equipped lab and is similar to a cardiac catheterisation procedure. Electrodes are placed inside the heart via a catheter placed into a vein. The electrodes are positioned near the heart's conduction system and an electrical map of the heart can be determined. This test is often performed in those where a life-threatening cardiac arrhythmia is a problem. The location and characteristics of an arrhythmia can be determined, thus guiding medical management of the problem. Patients with Wolf Parkinson White syndrome or sick sinus syndrome may have this test as part of their evaluation. Acronym: EPS (14 Mar 2000) |

| twin studies | Methods of detecting genetic aetiology in human traits. The basic premise of twin studies is that monozygotic twins, being formed by the division of a single fertilised ovum, carry identical genes, while dizygotic twins, being formed by the fertilization of two ova by two different spermatozoa, are genetically no more similar than two siblings born after separate pregnancies.
