Late/early RMS ratio may aid post-CABG AF risk stratification with age; leaves open prospective validation of P-wave signal averaging.
Does P wave signal averaging predict the risk of postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting?
P wave signal averaging, specifically the late/early RMS ratio, along with age, can help predict the risk of atrial fibrillation after coronary artery bypass surgery.
Dimmer et al. (1997) studied this question.
