Relias Dysrhythmia Basic Test Answers Solution guide 1. normal sinus rhythm 2. Sinus Arrhyth - mia 3. Sinus Bradycar - dia 4. Sinus Tachycar - dia 5. Premature Atri - al Contraction (PAC) 6. Sinus Ar - rest/Pause heart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) <60 normal sinus rhythm >100 (100 -150) normal sinus rhythm 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 pro- longed; can be different from other complexes QRS: <.12 seconds - 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) Relias Dysrhythmia Basic Test Answers Solution guide 7. Atrial Fibrillation (A-Fib) an irregular and often very fast heart rate originating from abnormal conduction in the atria 8. Atrial Flutter irregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to 1 block" 9. Junctional Rhythm 10. Junctional Tachy - cardia 11. Premature Junc - tional Contrac - tion 12. Supraventricular Tachycardia (SVT) 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) >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 Inverted p wave or hidden p wave PRI<0.12 or none Normal QRS an abnormal heart rhythm arising from aberrant electrical activity in the heart; originates at or above the AV node
