RELIAS DYSRHYTHMIA BASIC TEST ANSWERS
normal sinus rhythm
heart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute
Sinus Arrhythmia
Appearance is ALMOST NORMAL: Respiratory – Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
Sinus Bradycardia
<60

Premature Atrial 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 hidden within the T wave
PRI: measures between .12-.20 seconds and can be prolonged; can be different 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)
Atrial Fibrillation (A-Fib)
an irregular and often very fast heart rate originating from abnormal conduction in the atria
Atrial Flutter Relias Dysrhythmia Basic Test Answers 2023 Dysrhythmia –
Basic A ( A+ GRADED 100% VERIFIED)
irregular beating of the atria; often described as “a-flutter with 2 to 1 block or
3 to 1 block”
Junctional Rhythm
40-60 Regular!
-impulse from AV node w/ retro/antegrade transmission
–P wave often inverted/buried/follow QRS
–slow rate
–narrow QRS (not wide like ventricular)
Junctional Tachycardia
>60 bpm (ms. K; 150-250)
–KEY: will be regular (consistent)
–AV junction produces a rapid sequence of QRS-T cycles
–p-wave often inverted/buried/follow QRS
Premature Junctional Contraction
Inverted p wave or hidden p
wave PRI<0.12 or none
Normal QRS
