Atrial Flutter

Question 1

How is atrial flutter caused?

Answer 1

Originates in a single atrial focus, with the rhythm resulting from circus reentry and possibly increased automaticity

Question 2

What is the clinical significance of atrial flutter?

Answer 2

Determined by the number of impulses conducted through the AV node and the resulting ventricular rate
Cardiac output can be seriously compromised if the ventricular rate is too fast or too slow

Question 3

What rhythm has an abnormal P wave which produces a saw toothed appearance, a normal QRS and T waves that are hard to identify meaning that the QT interval and PR interval can’t be measured?

Answer 3

Atrial flutter

Question 4

How do you treat atrial flutter?

Answer 4

Calcium channel blockers, digoxin and amiodarone to control rate
Amiodarone or flecanide to convert the rhythm (under 48 hrs of onset and normal heart)
Synchronised cardioversion with anticoagulation

Question 5

What are the main nursing priorities with atrial flutter

Answer 5

Monitor pt closely for signs and symptoms of cardiac output
Keep resuscitation equipment at bedside
Be alert for the effects of digoxin (depresses the SA node)
Be alert for bradycardia

Question 6

What is atrial flutter?

Answer 6

A supra ventricular tachycardia, with the atrial rate of between 250-400 bpm
