Atrial Flutter Flashcards
1
Q
What is atrial flutter?
A
Irregular organised atrial firing (200-300 bpm), less common + less severe than AF
2
Q
RF?
A
Atrial fibrillation, also similar ethology to a fib
3
Q
Pathology?
A
Fast atrial ectopic firing (250-300bpm) causes atrial spasm but not as uncoordinated as A fib
Pathway typically from around tricuspid annulus (opening of valve)
4
Q
Sx?
A
Dyspnoea
Palpitations
5
Q
Dx?
A
ECG
F wave saw tooth pattern
often 3:1 block
3 p waves for every QRS
6
Q
Tx for acutely unstable?
A
DC synchronised cardio version
7
Q
Tx for stable a fib, to prevent further episodes?
A
Rhythm/rate control = beta blocker with oral anti coag (prevent thromboembolism)
Radiofrequency ablation
