ReliasDysrhythmiaBasic Test Answers Updated 2025
normalsinus rhythm
heart rhythm originating in the sinoatrial node with a rate in patients
restat
of 60 to 100 beats per minute
Sinus Arrhythmia
Appearance is ALMOST NORMAL:
Respiratory – Circulatory interaction
RateINCREASES withINSPIRATION (IN=IN)
Sinus Bradycardia
<60
,normalsinus rhythm
, Sinus Tachycardia
>100 (100-150)
normalsinus rhythm
PrematureAtrial Contraction(PAC)
Heart Rate: Depends on underlying rhythm
Regularity: Interrupts the regularity of underlying rhythm P-
Wave:can be flattened,notched,or unusual.May be hiddenwithin theT
wave
PRI: measures between .12
-.20 seconds and can be prolonged; can different
be
from other complexes
QRS: <.12 seconds
Sinus Arrest/Pause
– SA node doesn’t fire
– notice absence of P-wave for a complete cycle (a missed cycle) length
of pause ≠ multiple of normal rate (block)
