Background: The aim of this study was to evaluate atrial electromechanical delay (AEMD) with both electrocardiography
(ECG) and echocardiography in patients with Chronic Obstructive Pulmonary Disease (COPD).
Methods: Total of 110 patients were included in this cross-sectional case-control study. P-wave dispersion (PWD) was
measured on a 12-lead ECG. Atrial electromechanical intervals (PA) were measured as the time interval between the onset
of the P wave on the ECG and the beginning of the late diastolic A wave.
Results: PWD was found to be 40.9±9.2 ms in the healthy control group, 45.6±8.2 ms in the mild COPD and 44.8±8.7
ms in the severe COPD group (p<0.05). Intra-right atrial EMD was found to be 10.7±5.8 ms in mild COPD, 11.0±7 ms in
severe COPD, and it was 16.4±7.3 ms in healthy control group (p<0.001). Interatrial EMD was detected to be 29.5±9.1 ms
in the control group, 24.1±9 ms in mild COPD group, and 23.9±11.1 ms in the severe COPD group (p<0.001).
Conclusion: Both mild and severe COPD groups decreased PWD, increased tricuspid PA and significantly decreased interand
right intra-AEMD times in comparison to the control group.
