Basic Dysrhythmia-Relias CORRECT
SOLUTIONS HIGHLY GRADED A+
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
