Objective: This study investigate that the relationships are between electrocardiographic (ECG) parameters such as maximum and minimum P wave value (Pmax, Pmin), P wave dispersion (PWD) ), that can be obtained in a noninvasive manner with post coronary arteria bypass graft surgery (CABGS) atrial fibrillation (AF) development and to evaluate whether these parameters can be used to estimate the development of AF in postoperative patients who aren’t using beta blockers and recommended to have CABGS.

Material and Method: 100 patients, that are between ages of 35-75, not using beta blockers, with stable coronary artery disease (CAD), without arythmia and recommended to have a CABGS after coronary angiography, are included in the study. The preoperative ECGs of the patients are obtained from patient files and the condition of ability to measure the electrocardiographic parameters in least 9 of the 12 leads is looked for. All the measurements are done manually with a looking glass. The patients are divided into two groups according to postoperative AF development. Present risk factors, haemoglobin, haematocrit, cholesterols, fasting blood glucose, HbA1c levels, echocardiographic parameters significantly are recorded.

Results: Ages of the patients are between 35 and 75 (64.2±7.9), 14 are female (14%) and 86 are male (86%). 67 patients have hypertension (HT), 46 patients have diabetes mellitus (DM), 40 patients (40%) have hyperlipidemia (HL). The difference between Pmax and Pmin values that are obtained from preoperative ECGs of the patients are found to be greater in the patients that experienced postoperative AF.

Conclusion: Increased preoperative PWD is shown to be associated with increased early postoperative AF development.
