Pseudo atrial fibrillation – Cardiology MCQ
|Pseudo atrial fibrillation is seen in:
a) Mitral stenosis
b) Chronic obstructive pulmonary disease
c) Post cardiac transplant state
d) None of the above
Correct answer: c) Post cardiac transplant state
Atrial tachycardia in the donor atrial remnant can be conducted to the recipient heart at a variable rate, sometimes in Wenckebach sequence. Variable conduction across the suture line may cause atrial tachycardia to mimic atrial fibrillation, termed pseudo atrial fibrillation in the post cardiac transplant state [1].
