Regadenoson, sold under the brand name Lexiscan among others, is an A 2A adenosine receptor agonist that is a coronary vasodilator that is commonly used in pharmacologic stress testing. It produces hyperemia quickly and maintains it for a duration that is useful for radionuclide myocardial perfusion imaging . [ 1 ]
Pharmacologic agents such as adenosine, regadenoson (Lexiscan), or dipyridamole is generally used when a patient cannot achieve adequate work level with treadmill exercise, or has poorly controlled hypertension or left bundle branch block.

Methods in Molecular Biology is a book series published by Humana Press (an imprint of Springer Science+Business Media) that covers molecular biology research methods and protocols. The book series was introduced by series editor John M. Walker in 1983 and provides step-by-step instructions for carrying out experiments in a research lab. [1]
Although the use of wiki-type software has become common for a variety of purposes, several sources have questioned whether the wiki-based format of WikEM is reliable enough to use as a source for medical information, [3] with arguments similar to questions about the reliability of Wikipedia plus the additional concerns of patient safety.
