EKG RHYTHM RULES Questions with Correct Solutions


Question:
1. Normal Sinus Rhythm

Answer:
- Regularity: Regular R-R interval
- Rate: 60-100 bpm
- P Wave: upright, uniform shape; one P wave in front of every QRS complex
- PRI: 0.12-0.20 seconds and constant
- QRS: less than 0.12 seconds
- Positive T wave




Question:
2. Sinus Tachycardia

Answer:
- Regularity: Regular R-R interval
- Rate: Above 100 bpm
- P Wave: upright, uniform shape; one P wave in front of every QRS complex
- PRI: 0.12-0.20 seconds and constant
- QRS: less than 0.12 seconds
- Positive T wave




Question:
3. Sinus Bradycardia

Answer:
- Regularity: Regular R-R interval
- Rate: Below 60 bpm
- P Wave: upright, uniform shape; one P wave in front of every QRS complex
- PRI: 0.12-0.20 seconds and constant
- QRS: less than 0.12 seconds
- Positive T wave

, Question:
4. Narrow Complex Tachycardia or SVT

Answer:
- Regular rate
- Rate >150
- P waves unable to be found due to rapid rate
- PRI unable to be found due to rapid rate
- Narrow QRS <0.12 seconds
- T wave present




Question:
5. Atrial Fibrillation or A-Fib:

Answer:
- Regularity: grossly irregular
- Rate: atrial rate greater than 350 bpm; ventricular rate varies greatly
- P Wave: no discernible P waves
- PRI: unable to measure
- QRS: less than 0.12 seconds




Question:
6. Atrial Flutter

Answer:
- Regularity: atrial rhythm is regular; ventricular rhythm is usually regular but can be
irregular if there is variable block
- Rate: atrial rate 250-250 bpm; ventricular rate varies
- P Wave: characteristic sawtooth pattern
- PRI: unable to determine
- QRS: less than 0.12 seconds
