QUESTIONS WITH CORRECT DETAILED ANSWERS ||

100% GUARANTEED PASS <BRAND NEW VERSION>

heart block interventions .......Answer.........assess cardiac output


provide o2


if symptomatic : atropine , tcp w/ sedative


dopamine


epi


determine cause and eliminate


pvcs and 3rd degree block .......Answer.........good provide co, do

not use lidocaine


atrial pace maker .......Answer.........rhythm : regular if 1:1 pacing

,age 2 of 21




rate L varies on underlying


p wave : paced beats similar , pacing artifact before p wave


ventricular pacemaker .......Answer.........rhythm : regular for 1:1


p wave : may be present ,


qrs: paced bests are similar, with artifact before qrs


av sequential pacemaker .......Answer.........implanted pace maker

that stimulates the atrium to contract as well as the ventricles to

contract mimicking the normal action of the heart and preserving

the atrial kick


p wave dhould follow atrial spike


qrs should follow ventricular pacing spike

, age 3 of 21




firing/pacing .......Answer.........pacemaker has delivered a

stimulus and pacing artifact (spike) is seen on ECG


capturing heart .......Answer.........heart has responded to the

stimulus


electrical capture : pacing spike followed by p wave and qrs

wave ,


mechanical : cardiac depolarization followed by contraction


sensing pacemaker .......Answer.........ability of the pacemaker to

recognize the patient's intrinsic beats


sympathetic autonomic innervation of the heart

.......Answer.........releases epi, increases hr, CO and BP, Increased

firing of the SA node
