Key result
An atrial electromechanical interval cutoff of 115 ms detected postoperative atrial fibrillation with 100% sensitivity and 77% specificity in patients undergoing elective coronary artery bypass.
Why the study?
Does preoperative measurement of atrial electromechanical interval predict postoperative atrial fibrillation in patients undergoing elective coronary artery bypass grafting?
Observational (n=192)

p-value: p=<0.0001
Preoperative measurement of the atrial electromechanical interval using tissue Doppler echocardiography is a highly sensitive predictor of postoperative atrial fibrillation in patients undergoing elective CABG.
No takes yet. Share an insight, caveat, or question.
May support preoperative atrial electromechanical interval for POAF risk stratification in CABG; leaves open prospective validation.
Elawady et al. (2013) conducted an observational in Elective coronary artery bypass (n=192). Prolonged atrial electromechanical interval vs. Normal atrial electromechanical interval was evaluated on Postoperative atrial fibrillation (p=<0.0001). An atrial electromechanical interval cutoff of 115 ms detected postoperative atrial fibrillation with 100% sensitivity and 77% specificity in patients undergoing elective coronary artery bypass.
