pacemaker mode paces in the atria 100% of the time. No
sensing capability.
(post-op cardiac surgery or valvular surgery in presence
of AV block) -
ANSWER-
AOO
pacemaker mode paces the atria, sensing natural atrial activity,
and inhibits pacing if natural activity occurs. (Sinus node
dysfunction with good AV function, SB, sinus arrest, SA block,
afib) - ANSWER-AAI
pacemaker mode paces ventricles, senses natural ventricular
activity, and inhibitors pacing if natural ventricular activity
occurs. (Chronic afib, iatrogenic heart block with atrial
tacharrythmia, atrial paralysis, rare bradys) – ANSWER-VVI
pacemaker mode paces both atria and ventricles, senses both,
and inhibitors pacing when not needed. (brady interrupted by
,PSVT, sick sinus syndrome with intact AV conduct) - ANSWER-
DDI
pacemaker can pace both A/V, sense both, and can trigger
pacing when
needed or inhibited. (AV node disease, sinus node
dysfunction, atrial
arrhythmia) -
ANSWER-DDD
for idioventricular escape rhythm the HR< (), no p waves,
prolonged QRS
interval (ventricular/wide) -
ANSWER-50
for idioventricular agonal rhythm the HR is < () - ANSWER-20
lay patient on () side is preferred for transverse pacing wire -
ANSWER-left
symptoms of failure to capture - ANSWER-hypotension, brady,
fatigue
causes of failure to capture - ANSWER-metabolic imbalance,
physiologic issue
changes, drug
effects
,results in underpacing. Pacemaker too sensitive to other
signals and inappropriately considers it to be the desired
native wave it is looking for and does not pace. slower rate.
failure to pace. - ANSWER-oversensing
results in overpacing. pacemaker not sensitive enough by not
sensing patient onw rhythm and continues to pace when not
needed. - ANSWER-undersensing
symptoms of undersensing - ANSWER-palpitations, skipped
beats, may cause
vtach
vtach rate - ANSWER-110-250
normal QT interval - ANSWER-0.36-0.44
QT high limit - ANSWER-500
represents the total duration of depolarization and
depolarization of phases -
ANSWER-QT
interval
the higher the (), the shorter the QT interval - ANSWER-HR
three meds that increase QTI - ANSWER-Haldol, tikosyn,
amiodarone
, spike appears just before p - ANSWER-atrial pacing
spike appears just before qrs - ANSWER-ventricular pacing
spike appears before and after p - ANSWER-atrial and
ventricular pacing
atrial and ventricular pacing is aka what - ANSWER-dual
chamber pacing
indicated which chamber will be paced - ANSWER-1st letter
indicates which chamber is sensed by the pacemaking -
ANSWER-2nd letter
pacemakers response to sensing the patients natural heart
activity - ANSWER-
3rd
letter
Which ECG component represents atrial depolarization?
A. QRS complex
B. T wave
C. P wave
D. U wave
