Relias Dysrhythmia Basic Test 35 Questions and Answers 2024 (Basic A Dysrhythmia)
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 within
PRI: measures between .12-.20 seconds and can be prolonged; 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)
7.Atrial Fibrillation (A-Fib): an irregular and often very fast heart ra from abnormal conduction in the atria
8.Atrial Flutter: irregular beating of the atria; often described as "a-f 1 block or 3 to 1 block"
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
11.Premature Junctional Contraction: Inverted p wave or hidden PRI<0.12 or none
Normal QRS
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) Basic Dysrhythmia-Relias

12.Supraventricular Tachycardia (SVT): an abnormal heart rhythm aberrant electrical activity in the heart; originates at or above the AV n
