What is the half life of adenosine? - Correct Answer 10-15 seconds
What are the rules of adenosine dosage and admin? - Correct Answer -1st dose is 6 mg -If first dose does not work after 1-2 minutes, may give second dose of 12 mg -ALWAYS 20 ml flush
Why are multifocal PVCs more dangerous than unifocal PVCs? - Correct Answer Multifocal PVCs affect multiple areas of the heart, eventually leading to vtach
When are PVCs dangerous? - Correct Answer Frequent PVCs, multifocal, (2 in a row is a couplet) 3+ in a row (run of vtach), R on T
