Predisposing Factors
• Hx of AF• COPD• Intubation >24 hr• RCA lesion• High BNP level• Long P Wave
• Long cross clamp time
• Severe hypotermia• Reaction of anterior
epicardial fat pad• Right atrial pacing

Evaluated Factors
• Age • DM• HTN• CS• LA volume• RA volume• LV end-diastolic volume• RV end-diastolic volume • PA pressure
• LM lesion• LAD lesion• LCx lesion• RCA lesion• Total coronary arteries
diameter(TCD)• Ratio of LADd/TCD ,
RCAd/TCD , LCxd/TCD• Cross clamp time
