Sinus rhythm:
Regularity
Regular
What are four categories of Arrhythmias of the sinus node?
Normal sinus rhythm
Sinus bradycardia
Sinus tachycardia
Sinus arrhythmia
Sinus rhythm:
Rate
60-100
Sinus rhythm:
P wave regularity
Uniform
Infront of every QRS complex
Sinus rhythm:
PRI time
.12-.20 second
Sinus rhythm:
QRS time
Less than .12 second
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 tachycardia?
It follows all the rules for normal sinus rhythm except greater than 100 heart rate

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