Cardiology MCQ 372: Hypothermia for post op arrhythmia
Hypothermia is used for treatment of which post operative arrhythmia?
a) Complete heart block
b) Atrial fibrillation
c) Junctional ectopic tachycardia
d) None of the above
["Click here for the answer with explanation", "Correct Answer:"]
c) Junctional ectopic tachycardia
Junctional ectopic tachycardia (JET) is a unique postoperative arrhythmia, especially in children after cardiac surgery. JET is often difficult to treat. It is likely to recur after cardioversion. Sedation and cooling (hypothermia) are helpful. Read more on post operative cardiac arrhythmias…
