Flashcards in Atrial Flutter Deck (12)
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.
What is the atrial rate in atrial flutter.
What are the principal types of AV block found in atrial flutter (2)
What are the symptoms of atrial flutter. (3)
What are the main causes of atrial flutter. (2)
Acute cardiac or respiratory problems. (eg pericarditis, pneumonia).
What are the clinical signs of atrial flutter. (2)
Tachycardia, with or without haemodynamic compromise.
What is typically seen on the ECG of a patient with atrial flutter. (2)
Characteristic sawtooth pattern.
With AV block.
What is the main investigation for a patient with atrial flutter.
What are the two main aspects of treatment of atrial flutter. (2)
What drug groups are used for rate control in atrial flutter. (2)
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.
