lower HR and BP - ✔✔ANSW✔✔..beta blockers
2 consecutive PVCs - ✔✔ANSW✔✔..couplet
3 consecutive PVCs - ✔✔ANSW✔✔..triplet
a pt in V-tach is at risk for - ✔✔ANSW✔✔..drop in CO, v-fib, death
a pt in V-tach is unresponsive. the priority intervention is - ✔✔ANSW✔✔..CPR,
defibrillation
a pt in VT is at risk for - ✔✔ANSW✔✔..V-fib
all PVCs going in the same direction; it's the same spot firing - ✔✔ANSW✔✔..unifocal

problems can't use
amiodarone SE on lab values and EKG - ✔✔ANSW✔✔..inc INR, digoxin, longer QT
interval
are PVCs always harmful? - ✔✔ANSW✔✔..only harmful if symptomatic
atrial flutter/fibrillation Tx - ✔✔ANSW✔✔..CCB, BB, electrical cardioversion,
amiodarone
, atrial tachydysrhymia
recurring, regular, COARSE, SAWTOOTH-SHAPED waves
caused by one single point in the R atrium
regular rhythm
PR interval unmeasurable
QRS normal
may see some AV block - ✔✔ANSW✔✔..atrial flutter
ectopic stimuli on ventricles fire prematurely.
early QRS with no P waves.
irregular rhythm
wide QRS: >.12 seconds
large T wave in the opposite direction of the QRS.
compensatory pause afterward - ✔✔ANSW✔✔..PVC
how does v-tach drop CO? - ✔✔ANSW✔✔..less ventricular diastole filling time, no atrial
contraction
