2025 Relias telemetry test answers
When is a pacemaker used - ansPost-op cardiac surgery, for tachydysrhythmias, for
effects of medications
What arrhythmias may require a pacemaker - ansSymptomatic AV blocks:
Ventricular paced rhythm - ansventricular contractions which occur in cases of complete
heart block.
Ventricular fibrillation (V-fib) - ansabnormal heart rhythm which results in quivering of
ventricles
Ventricular depolarization
Torsades de pointes - ansRate: 120 - 200 usually
-third degree heart blocks
T wave represents - ansVentricular repolarization
Symptomatic sinus node dysfunction:
Sympathetic branch - ansAffects both the atria and ventricles. Increases HR,
conduction, and irritability
Supraventricular Tachycardia (SVT) - ansan abnormal heart rhythm arising from
aberrant electrical activity in the heart; originates at or above the AV node
Sudden appearance of a nonconducted P-wave
Sinus Tachycardia - ans>100 (100-150)
Sinus Bradycardia - ans<60
-sinus block
Sinus Arrhythmia - ansAppearance is ALMOST NORMAL:
Sinus Arrest/Pause - ans- SA node doesn't fire
-sinus arrest
-sick sinus syndrome
-second degree type II
-second degree type I
Rhythm: Slightly irregular
Rhythm: Regular
Respiratory - Circulatory interaction
Represents both atrial depolarization & delay in AV node
Regularity: Interrupts the regularity of underlying rhythm
Rate INCREASES with INSPIRATION (IN=IN)
QRS: Wide QRS - "Twisting of the Points"
QRS: Wide QRS
QRS: <.12 seconds
QRS - ansLess than 0.12 seconds
P-waves are nl, but some aren't followed by a QRS complex
P-Wave: can be flattened, notched, or unusual. May be hidden within the T wave
PVC couplets - ansPVC occurring in pairs, no adequate C.O. when this occurs
PRI<0.12 or none
PRI: measures between .12-.20 seconds and can be prolonged; can be different from
other complexes
PRI - ans0.12-0.20 seconds
premature ventricular contraction (PVC) - ansa ventricular contraction preceding the
normal impulse initiated by the SA node (pacemaker)
