BASIC DYSRHYTHMIA-RELIAS MEDICAL EMERGENCY 2023 QUESTIONS AND ANSWERS (RELIAS) heart rhythm originating in the sinoatrial node with a ratein patients at rest of 60 to 100 beats per minute ... 1. Sinus Arrhyth- mia Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) 2. Sinus Bradycar-dia <60 normal sinus rhythm 3. Sinus Tachycar-dia >100 (100-150) normal sinus rhythm 4. Premature Atri-al Contraction (PAC) Heart Rate: Depends on underlying rhythm Regularity: Interrupts the regularity of underlying rhythmP-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 5. Sinus Ar- rest/Pause - SA node doesn't fire - notice absence of P-wave for a complete cycle (a missedcycle) length of pause ` multiple of normal rate (block) 6. Atrial Fibrillation(A- Fib) an irregular and often very fast heart rate originating fromabnormal conduction in the atria 7. Atrial Flutter irregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to 1 block" 8. Junctional Rhythm 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) 9. JunctionalTachy- cardia >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 10. Premature Junc- tional Contrac- tion Inverted p wave or hidden p wave PRI<0.12 or none Normal QRS 11. Supraventricular Tachycardia (SVT) an abnormal heart rhythm arising from aberrant electrical activity in the heart; originates at or above the AV node 12. First degree heart block atrioventricular (AV) block in which the atrial electrical impulses are delayed by a fraction of a second beforebeing conducted to the ventricles 13. 2nd degree heart block type 1 (Wenkebach) Progressively longer PR interval until the P wave is notfollowed by a QPR 15.15. 2nd Degree Heart Rare, but more serious Block (Mobitz II) Sudden appearance of a nonconducted P-wave P-waves are nl, but some aren't followed by a QRS com-plex PR & RR intervals are constant [Show More]
