Interpretation - 313 - Sinus Rhythms.
- The previous slides presented the five-steps of rhythm analysis. These five steps must be followed regardless of how simple of complex the tracing is you are reviewing.
- The information gathered in these steps are telling a story.
- The title of that story is the interpretation.
Sinus Rhythm Types
The dysrhythmias in this category occur as a result of influences on the Sinoatrial (SA) node. Rhythms in this category will share similarities in a normal appearing P wave, the PR interval will measure in the “normal range” of 0.12 – 0.20 second, and the QRS typically will measure in the “normal range” of 0.06 – 0.10 second. For the most part, dysrhythmias in this category either effect the rate, rhythm regularity or both within a particular tracing. We will be discussing the following complexes and rhythms:
- Normal Sinus Rhythm
- Sinus Bradycardia
- Sinus Tachycardia
- Sinus Dysrhythmia (Arrhythmia)
- Sinus Arrest
- Sinus Exit Block
