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

7

Regular

8

Sinus bradycardia
Rate

What is sinus arrhythmia?

It follows the rules of normal sinus rhythm except the rate changes with the pts respirations
