Flashcards in Atrial Flutter Deck (12):
1

What is atrial flutter. (2)

Atrial re-entry tachycardia, leading to a rapid atrial rate. ( approximately 300beats/min).
Usually occurs with a slower ventricular rate due to 2:1 or 3:1 block in the AV node.

2

What is the atrial rate in atrial flutter.

Approximately 300BPM.

3

What are the principal types of AV block found in atrial flutter (2)

2:1.
3:1.

4

What are the symptoms of atrial flutter. (3)

Palpitations.
Dizziness.
Heart failure.

5

What are the main causes of atrial flutter. (2)

Acute cardiac or respiratory problems. (eg pericarditis, pneumonia).

6

What are the clinical signs of atrial flutter. (2)

Tachycardia, with or without haemodynamic compromise.

7

What is typically seen on the ECG of a patient with atrial flutter. (2)

Characteristic sawtooth pattern.
With AV block.

8

What is the main investigation for a patient with atrial flutter.

ECG.

9

What are the two main aspects of treatment of atrial flutter. (2)

Rate control.
Curative.

10

What drug groups are used for rate control in atrial flutter. (2)

Anti-arrhythmics.
Anticoagulation.

11

What are the curative methods of treating atrial flutter. (4)

DC cardioversion (anticoagulant before).
Anti-AF drugs might not work, but consider amiodarone to restore sinus rhythm, and amiodarone or sotalol to maintain it (if IV route is needed, a beta blocker might be preferred).
Catheter ablation of aberrant pathway.

12

If you are unsure if a patient is suffering from atrial flutter, what two things might unmask the sawtooth waves on an ECG. (2)

Carotid sinus massage.
IV adenosine.
