Cardiac Rhythm Review

Front

Step #1: Rate=

Back

Most dysrhythmias have rate criteria.

Front

Step 2: Rhythm=

Back

Check if the rhythm is regular or irregular. If irregular, determine if there is a pattern.

Front

P-wave morphology is...

Back

Examine what the P-wave looks like and if a QRS follows every P-wave.

Front

PR-interval

Back

Determine if the PR-interval is normal. Normal range is 120-200 ms. Check if it is the same in every complex.

Front

QRS morphology

Back

Assess if the QRS morphology is normal. Normal range is 60-120 ms.

Front

Sinus = SA ?

Back

The sinus node, or SA node, is associated with an upright, rounded P-wave.

Front

NSR =

Back

Normal sinus rhythm (NSR) ranges from 60 to 100 beats per minute.

Front

Sinus bradycardia =

Back

Sinus bradycardia is characterized by a heart rate of less than 60 beats per minute.

Front

Sinus tachycardia is...

Back

Sinus tachycardia is defined by a heart rate between 101 and 150 beats per minute.

Front

Sinus dysrhythmia =

Back

Sinus dysrhythmia involves the heart rate slowing and speeding up with respirations.
