Do preoperative electrocardiographic parameters predict new-onset atrial fibrillation in patients undergoing coronary artery bypass grafting?
Preoperative assessment of specific P wave and T wave morphology parameters on ECG can independently predict the risk of new-onset atrial fibrillation following CABG.
Gang et al. (2004) conducted an observational in Patients undergoing primary elective and isolated CABG without a history of atrial fibrillation (n=151). Preoperative electrocardiographic parameters (P wave and T wave morphology) vs. Normal preoperative ECG parameters was evaluated on New-onset atrial fibrillation after CABG. Preoperative ECG parameters, including increased integral of P wave (P=0.038) and reduced total cosine R to T (P=0.040), independently predicted new-onset atrial fibrillation after CABG.
