Exam 1: NR 341/ NR341 Complex Adult Health Exam 1 Review | Guide with Verified Answers | Newly Updated 2023/ 2024-- Chamberlain Question Cardioversion vs Defibrillation Answer: Cardioversion: in sync with QRS, used in AFib, atrial flutter, VT w/ a pulse, SVT Defibrillation: (random shock) - not in sync with QRS, used in VFib and VT without a pulse Question treatment for new onset A-F...

What does the SA node initiate - - P wave (if none, SA not responsible for electrical conduction) (atrial depolarization) What does the QRS complex represent? - ventricular depolarization (vent contraction) (none=no pulse) (don't see atrial repolarization but it occurs, as it is not the strongest thing to occur) What does the U wave indicate? - indicates hypocalemia, not conductio issue it would be seen with electrolyes (digoxin) Is it normal to not see part of the Q, R, or S complex -...
