Abstract:Background
Use of adenosine triphosphate (ATP) instead of adenosine in stress echocardiography is more cost-effective. Earlier we have proposed new ATP stress echocardiography algorithm (Figure). This modified algorithm includes 1) stepwise increase in dose of ATP in the absence of signs of adequate vasodilation (decrease in systolic blood pressure and increase in heart rate), 2) triple registration of echocardiographic data sets (before ATP infusion, during phase of adequate vasodilation and… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
