I recently started working at a cardiology practice in August. They had just started using Lexiscan & I love it. Pt's don't complain nearly as bad as they did with Adenosine. Mild SOB, some nausea. You can use on pt's with asthma-not if actively wheezing. I am interested in your practice. You stated the nurses run the tests.Do you not have to have a PA or NP to monitor EKG? We do, but our administrator is interested in the nurses doing it. Do you know of a course to become certified? Thanks!
