Answers) Solved 100% Correct!! Basic Dysrhythmia-Relias
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
Atrial Flutter - answer☑️✔️...irregular beating of the atria; often described as "a-flutter with 2
to 1 block or 3 to 1 block"
Junctional Rhythm - answer☑️✔️...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 - answer☑️✔️...>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 - answer☑️✔️...Inverted p wave or hidden p wave
PRI<0.12 or none
Normal QRS
Supraventricular Tachycardia (SVT) - answer☑️✔️...an abnormal heart rhythm arising from
aberrant electrical activity in the heart; originates at or above the AV node
First degree heart block - answer☑️✔️...atrioventricular (AV) block in which the atrial electrical
impulses are delayed by a fraction of a second before being conducted to the ventricles
