NUR 426 Lecture Notes - Lecture 15: Torsades De Pointes, Bag Valve Mask, Cardiac Arrhythmia
Document Summary
Cardiac emergency medications: types of cardiac emergencies, acute myocardial infarction/acute coronary syndromes, disturbances in heart rate & rhythms, symptomatic bradycardia, unstable tachycardia, dysrhythmias. Atropine sulfate speeds up the heart; used to treat symptomatic bradycardia (lethargy, dizzy), can treat heart block but depends. Adenosine used to treat svt (a-tach); works between the sa and the av node.
