Most common sustained post-operative arrhythmia – MCQ – Answer

Most common sustained post-operative arrhythmia – Correct answer: b) Atrial fibrillation

Atrial fibrillation is also the most common sustained arrhythmia in the general population.

Post-operative atrial fibrillation (AF) is mostly due to the enhanced sympathetic activity. It can be precipitated by fever, sepsis, myocardial ischemia and beta stimulants given for bronchospasm which is common in the perioperative period. Post-operative increases the morbidity and length of hospital stay as well as stay in the intensive care unit.

Isolated atrial and ventricular ectopics are common in post-operative period, but are not sustained arrhythmia.
