Flashcards in MED-SURG---Cardiac Rhythm & Dysrhythmias Deck (64)
What is a PREMATURE COMPLEX?
Occurs when a cell other than the SA NODE becomes irritable and fires off an impulse.
**Because of automaticity, these cells can depolarize by themselves
DECREASED VENTRICULAR FILLING = DECREASED CARDIAC OUTPUT
Complications of A-Fib (2)
1) Blood pooling in atria can lead to thrombus / clot formation increasing risk of stroke , MI, PE
2) If HR is too rapid and irregular, ventricular filling time is decreased so cardiac output decreases
Clinical Symptoms of Dysrhythmias / poor perfusion
"WASP HAD CPU"
U-rine is decreased
