BASIC DYSRHYTHMIA-RELIAS

2. Sinus Arrhythmia: Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) 3. Sinus Bradycardia: 60 normal sinus rhythm 4. Sinus Tachycardia: 100 (100-150) normal sinus rhythm 5. Premature Atrial Contraction (PAC): Heart Rate: Depends on underlying rhythm Regularity: Interrupts the regularity of underlying rhythm P-Wave: can be flattened, notched, or unusual. May be hidden withi PRI: measures between .12-.20 seconds and can be prolonged; can be different from other complexes QRS: .12 seconds 6. Sinus Arrest/Pause: - 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) 7. Atrial Fibrillation (A-Fib): an irregular and often very fast heart ra from abnormal conduction in the atria 8. Atrial Flutter: irregular beating of the atria; often described as "a to 1 block or 3 to 1 block" 9. 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) 10. Junctional Tachycardia: 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 12. Supraventricular Tachycardia (SVT): an abnormal heart rhyth aberrant electrical activity in the heart; originates at or above the AV 13. First degree heart block: atrioventricular (AV) block in which the cal impulses are delayed by a fraction of a second before being co ventricles 14. 2nd degree heart block type 1 (Wenkebach): Progressively lo val until the P wave is not followed by a QPR 15. 2nd Degree Heart Block (Mobitz II): Rare, but more serious Sudden appearance of a nonconducted P-wave P-waves are nl, but some aren't followed by a QRS complex PR & RR intervals are constant 16. 3rd degree heart block: no obvious correlation between p and q maker 17. premature ventricular contraction (PVC): a ventricular contra ing the normal impulse initiated by the SA node (pacemaker) 18. Bigeminy PVC: every other beat is a PVC 19. PVC couplets: PVC occurring in pairs, no adequate C.O. when 20. monomorphic ventricular tachycardia: presents with wide Q of a common shape. 21. Torsades de pointes: Rate: 120 - 200 usually P wave: Obscured by ventricular waves QRS: Wide QRS - "Twisting of the Points" Conduction: Ventricular only Rhythm: Slightly irregular 22. Ventricular fibrillation (V-fib): abnormal heart rhythm which re ing of ventricles 23. Idioventricular Rhythm: 40 *looks like vtach but slow* - no P waves (from vent foci) - Wide QRS (serious, death like rhythm) - called "dying heart" rhythm...occasional ventric beat b4 death (asystole) 24. Accelerated Idioventricular Rhythm: Rate: 50 - 100 usually (usually slow) P wave: Obscured by ventricular waves (occur during ventricular contraction) - SA node slower than faster ventricular pacing than should be QRS: Wide QRS Conduction: Ventricular only Rhythm: Regular - benign rhythm that is sometimes seen during acute MI or early after reperfusion. - Rarely sustained, does not progress to vfib, rarely requires treatment 25. asystole: absence of contractions of the heart 26. Failure to capture (pacemaker): 27. failure to sense (pacemaker): 28. Atrial paced rhythm: spike before P wave 29. Ventricular paced rhythm: ventricular contractions which occu
