ECG Analysis: Rhythm Recognition (Relias)
1. What is the normal PR interval for an atrial fibrillation rhythmAns: Not applicable
2. Which of the following measures the time from the start of atrial depolariza- tion to
the start of ventricular depolarizationAns: PR Interval
3. Which of the following is associated with sinus tachycardiaAns: anxiety, fear, pain
4. What is the normal duration for the PR intervalAns: 0.12-0.20
5. What is characteristic of standard ECG paperAns: Comprised of small boxes
measuring 0.04 seconds
6. Which rhythm occurs when the atrial rate and ventricular rate occur inde-
pendentlyAns: Third Degree Block
7. What is a characteristic of sinus bradycardiaAns: less than 60 bpm
8. What part of the heart is the origin of an idioventricular rhythmAns: Ventricles
9. What ECG rhythm has no discernible P waves, irregular fibrillatory waves, and
an irregular R to R intervalAns: Atrial fibrillation
10. What helps determine if a patient is Â"toleratingÂ" a rhythmAns: Blood pres-
sure and level of consciousness
11. What part of the heart ejects blood into the aortaAns: Left Ventricle
12. When placing a 5 lead ECG on a patient, which lead would be placed on the
right 4th intercostal spaceAns: V
13. True or False: Multifocal Atrial Tachycardia is caused by at least three ectopic
atrial pacemakers and has a rate of greater than 100 beats per minute.-
: True
14. What is a potential cause of PVCsAns: Hypokalemia
15. What type of AV block is associated with progressively longer PR intervals and an
eventual Â"droppedÂ" QRS complexAns: Second Degree Type-1
16. How long is a normal QRS complexAns: less than 0.12 seconds
