BASIC DYSRHYTHMIAS I 2023 GRADED A+ VERIFIED

1. A dysrhythmia is any alteration in of heart from normal beat: Electri- cal conduction 2. Atrial dysrhythmia has an impulse from the:: Atrium 3. Junctional dysrhythmia has an impulse from the:: Area surrounding the AV node 4. Ventricular dysrhythmia has an impulse from the:: Ventricle 5. Bradycardia is a HR of BPM at rest: Slow Less than 60 6. Tachycardia is a HR of BPM at rest: Fast Greater than 100 7. In a normal conducting heart, electrical impulse begins in the : SA Node 8. In a heart with dysrhythmia, electrical impulse begins : Anywhere else but the SA node 9. A is any electrical impulse that fires earlier than expected: Premature contraction 10. Premature contractions are some impulse from that fires before SA node: Anywhere in the heart 11. A is a rhythm categorized by 4 R's: Flutter 12. What are the 4 R's of flutter?: Rhythm with rapid, regular, repetitive rate 13. A flutter is BPM at rest and can be from the : 250-350 Atria or ventricles 14. is a quivering of the chambers because of inadequate electrical stimulation: Fibrillation 15. During a fibrillation there is no and the ventricles will not : - Contraction Pump blood to the body 16. A is a delay in electrical conduction at level of AV node or within ventricles: Heart block 17. An is having no or a lock of electrical stimulation: Arrest 18. An arrest is the easiest to identify because it is just a , but it is very difficult to : Flat line Manage 19. In normal sinus rhythm, how are the atrial rate and ventricular rate relat- ed?: Atrial = ventricular 20. In an EKG, the x-axis represents , with 1 little block being mm or seconds, and 1 big block being seconds: Time 1 0.04 0.2 21. In an EKG, the y-axis represents , with 1 little block being or mV: Amplitude 1 1 22. What are the characteristics of an EKG?: P-wave QRS interval PR interval ST segment and T wave 23. What 4 things do you look for in a P-wave?: Is there one in every cardiac cycle? Do they all look the same? Atrial rhythm Atrial rate 24. If all P-waves look the same, they are all from the : SA node 25. If even ONE P-wave is different, where is it from?: Not the SA node 26. How do you measure atrial rhythm?: P-P spacing 27. What does consistent P-P spacing represent? Changing?: Regular atrial rhythm Irregular atrial rhythm 28. How do you measure atrial rate?: # of P-waves in 6 seconds x 10 29. What 4 things do you look for in a QRS complex?: Is there one in every cardiac cycle?
