Basic Dysrhythmia-Relias TEST
QUESTIONS AND VERIFIED
ANSWERS BY EXPERTS 2023
, 1. normal sinus rhythm: heart rhythm originating in the sinoatrial node
with a rate in patients at rest of 60 to 100 beats per minute
2. Sinus Arrhythmia: Appearance is ALMOST
NORMAL: Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3. Sinus Bradycardia:
<60 normal sinus
rhythm
4. Sinus Tachycardia: >100 (100-
150) normal sinus rhythm
5. 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 n thewithi
T
PRI: measures between .12-.20 seconds and can be prolonged; wave can be
different from other complexes
QRS: <.12 seconds
6. 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)
ate r
7. Atrial Fibrillation (A-Fib): an irregular and often very fast heart
g from abnormal conduction in the atria originatin
8. Atrial Flutter: irregular beating of the atria; often -flutter
described as "a to 1 block or 3 to 1 block" with 2
9. 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)
10.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
