Case-control study on atrial electromechanical coupling time in patients with new-onset postoperative atrial fibrillation.

ABSTRACT: Atrial electromechanical coupling time (AEMCT) can be used to evaluate atrial electrical remodeling and early structural remodeling. This study explores the predictive role of AEMCT in postoperative new-onset AF (POAF) after off-pump isolated coronary artery bypass grafting (OPCAB). A total of 116 patients who underwent OPCAB and left atrial diameter (LAD)<44 mm were analyzed. According to 7-day continuous telemetry and Holter monitoring after OPCAB, the patients were divided into POAF group and non- POAF group. Patients were divided into two groups according to whether new-onset POAF occurred, namely, POAF group (38, 32.7%) and non-POAF group (78, 67.3%). There was no significant difference in LAD between two group. Multivariate analysis found that P-A_LA ( P wave on ECG to the
