Normal sinus rhythm Flashcards
1
Q
what is the parameters for a normal P wave?
A
smooth, round, 0.08 to 0.10 sec
2
Q
what is the parameters for a normal QRS complex?
A
0.06 to 0.12 sec
3
Q
what is the parameters for a normal T wave?
A
never taller than 2/3 of QRS
4
Q
what is the definition of a NSR (8)
A
- Rhythm is regular
- rate is 60 – 100 beats per minute (bpm)
- P-wave is upright with normal rounded morphology
- P-R interval is 0.12 - 0.20 seconds
- QRS width is 0.06 – 0.12 sec
- A QRS complex follows every p – wave
- A P-wave precedes every QRS complex
- A T-wave follows every QRS complex
