BSMH Advanced Arrhythmia Questions with 100% Correct Answers

BSMH Advanced Arrhythmia Questions with 100% Correct Answers 1. Ventricular tachycardia - ANSWER marching nuns 2. Torsades de pointes - ANSWER Rate 200, no P waves, wide QRS 3. Ventricular fibrillation - ANSWER Rate cannot be counted 4. Idioventricular - ANSWER Rate 20-40 5. T wave opposite QRS, no P wave, wide QRS 6. Accelerated Idioventricular - ANSWER Rate 40-100 T wave opposite QRS, no P wave, wide QRS 7. Asystole - ANSWER Flat line 8. First degree heart block - ANSWER Prolonged P wave 0.20 "If R is far from P, then you have a 1st degree" 9. Second degree heart block, type 1 - ANSWER Increasingly larger PR intervals "Longer, longer, longer block, now you have a Wenckebach" 10. Second degree heart block, type 2 - ANSWER PR constant on the conducted beats "Some P's don't get thru then you have a Mobitz II" 11. Third degree heart block - ANSWER PR varies "If P's and Q's just don't agree, then we have a third degree" 12. Pacemaker Failure to Capture - ANSWER Pacemaker spikes not followed by P wave or QRS complex 13. Pacemaker Failure to Sense - ANSWER Pacemaker spike occurs in middle of QRS complex, T wave, or ST segment 14. Conduction pathway - ANSWER Sinus node - inerarterial tracts - atrium - intermodal tracts - AV node - bundle of HIS - bundle branches - purkinje fibers - ventricles 15. Inherent rates - ANSWER SA node = 60-100 AV node = 40-60 Ventricle = 20-40 16. Atrial flutter - ANSWER Sawtooth pattern 17. Atrial fibrillation - ANSWER Waves between QRS 18. Supraventricular tachycardia - ANSWER No P wave, rate 150 19. Junctional rhythms - ANSWER P wave inverted or absent Junctional bradycardia: 40 Junctional rhythm: 40-60 Accelerated junctional: 60-100 Junctional tachycardia: 100 20. Blood flow through the heart - ANSWER SVC -- Rt atria -- Tricuspid -- Rt ventricle -- Pulmonic valve -- Lungs -- Lt atria -- Mitral valve -- Lt ventricle -- aortic valve -- aorta -- Body 21. EKG Times - ANSWER 6 second strip 1 small block = 0.04 secs 1 big block = 5 small boxes = 0.20 secs 15 big blocks = 3 seconds 22. P Wave - ANSWER atrial depolarization 23. PR Interval - ANSWER time it takes for the impulse to get from atrial to ventricles 0.12 - 0.20 seconds 24. QRS Interval - ANSWER ventricular depolarization 0.12 seconds 25. ST Segment - ANSWER early depolarization of ventricles depression = myocardial infarction elevation = myocardial injury 26. T Wave - ANSWER repolarization of ventricles 27. Heart blocks - ANSWER No changes in PR Interval - QRS complexes present = 1st degree - No QRS complexes = 2nd degree type II Changes in PR Interval - R to R interval regular = 3rd degree - R to R interval irregular = 2nd degree type I
