Objective:
To assess P-wave duration and dispersion (PD) in morbidly obese young subjects who do not have co-associated atrial fibrillation (AF) risk factors, such as hypertension, diabetes, atrial enlargement and diastolic dysfunction.
Study Design:
An observational cross-sectional study.
Place And Duration Of Study:
Bolu Abant Izzet Baysal University Medical Faculty, Turkey; and the study was conducted between October 2017 and June 2018.
Methodology:
P-wave duration and dispersions were determined on 12-lead surface ECG in 47 morbidly obese and 44 healthy weight subjects, aged between 21-40 years. Above mentioned risk factors were studied. The correlation between BMI, PD and Pmax were investigated by Pearson correlation analysis. Results: Average body mass index (BMI) of obese and control groups were 42.3 (8.5) vs. 19.5 (1.5) (P <0.001). Maximum P-wave duration [(Pmax), 105.3±9.8 vs. 95.6±8.5, p<0.001] and PD [27.6 (7.6) vs. 12.2(8.3), p<0.001] were statistically significantly prolonged in obese patients when compared to the normal weight group. BMI correlation with Pmax and PD (r=0.485; p<0.001 and r=0.620; p<0.001, respectively) were significant.
Conclusion:
Pmax and PD, which are potential electrocardiographic AF predictors, may increase in lone obese patients having no comorbidities. Key Words: Electrocardiography, Arrhythmia, P-wave duration, P-wave dispersion, Severe obesity.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
