BASIC DYSRHYTHMIA-RELIAS
VERIFIED EXAM QUESTIONS AND
ANSWERS
normal sinus rhythm - Correct Answers-heart rhythm originating in the sinoatrial node with a rate in
patients at rest of 60 to 100 beats per minute
Sinus Arrhythmia - Correct Answers-Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
Sinus Bradycardia - Correct Answers-<60
normal sinus rhythm
Sinus Tachycardia - Correct Answers->100 (100-150)
normal sinus rhythm
Premature Atrial Contraction (PAC) - Correct Answers-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 - Correct Answers-- 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) - Correct Answers-an irregular and often very fast heart rate originating from
abnormal conduction in the atria
Atrial Flutter - Correct Answers-irregular beating of the atria; often described as "a-flutter with 2 to 1
block or 3 to 1 block"
Junctional Rhythm - Correct Answers-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 - Correct Answers->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 - Correct Answers-Inverted p wave or hidden p wave
PRI<0.12 or none
Normal QRS
Supraventricular Tachycardia (SVT) - Correct Answers-an abnormal heart rhythm arising from aberrant
electrical activity in the heart; originates at or above the AV node
First degree heart block - Correct Answers-atrioventricular (AV) block in which the atrial electrical
impulses are delayed by a fraction of a second before being conducted to the ventricles
