What are four categories of Arrhythmias of the sinus node?
Normal sinus rhythm
Sinus bradycardia
Sinus tachycardia
Sinus arrhythmia
1
Sinus rhythm:
Regularity
Regular
2
Sinus rhythm:
Rate
60-100
3
Sinus rhythm:
P wave regularity
Uniform
Infront of every QRS complex
4
Sinus rhythm:
PRI time
.12-.20 second
5
Sinus rhythm:
QRS time
Less than .12 second
6
When is a rhythm sinus bradycardia?
If it follows all the rules of normal sinus rhythm EXCEPT the rate is less than 60

What is sinus arrhythmia?
It follows the rules of normal sinus rhythm except the rate changes with the pts respirations
19
In a sinus arrhythmia what happens when the pt breathes in?
The rate increases
