2. Fig 1
Results of analysis of atrial areas. Data are shown as mean values and error lines indicate one standard deviation. Open bars are patients maintaining sinus rhythm and black bars are patients developing atrial fibrillation. All p values are less than 0.05 within the groups, preoperatively and on Day 2, but all p values are not significant between the two patients groups. (Preop = preoperative.)

3. Fig 2
Results of analysis of atrial peptides. Data are shown as mean values and error lines indicate one standard deviation. Open bars are patients maintaining sinus rhythm and black bars are patients developing atrial fibrillation. All p values are less than 0.05 within the groups, preoperatively and on Day 2, but all p values are not significant between the two patients groups. (pg/mL = picogram per milliLiter; pmol/L = picomol per Liter; preop = preoperative.)
