Relias Dysrhythmia Basic Test Answers 2023 Dysrhythmia – Basic A ( A+ GRADED 100%
VERIFIED)
normal sinus rhythm - (ANSWER)heart rhythm originating in the sinoatrial node with a rate
in patients at rest of 60 to 100 beats per minute
Sinus Arrhythmia - (ANSWER)Appearance is ALMOST NORMAL: )(*&^%$
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
Sinus Bradycardia - (ANSWER)<60
normal sinus rhythm
Sinus Tachycardia - (ANSWER)>100 (100-150)
normal sinus rhythm
Premature Atrial Contraction (PAC) - (ANSWER)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 - (ANSWER)- 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) - (ANSWER)an irregular and often very fast heart rate originating
from abnormal conduction in the atria
