Implication
May identify higher-risk CABG patients for monitoring; hypothesis-generating and requires prospective validation before practice change.
Structured PICO

P
Population
102 patients before coronary artery bypass grafting
I
Intervention
Pre-operative assessment of vagal tone (vagal index < 10%) and supraventricular ectopic activity via 24-h Holter monitoring
C
Comparator
Patients with normal vagal tone and lower supraventricular ectopic activity
O
Outcome
Development of atrial fibrillation or flutter after coronary artery bypass surgeryhard clinical
Attenuated pre-operative cardiac vagal modulation and supraventricular ectopic activity are independent risk factors for developing atrial fibrillation or flutter after CABG.
