Key result
Chronic obstructive pulmonary disease was associated with significantly decreased interatrial electromechanical delay (23.9 ms in severe COPD vs 29.5 ms in controls) and increased P-wave dispersion.
Why the study?
The study was conducted to evaluate atrial electromechanical delay with electrocardiography and echocardiography in patients with chronic obstructive pulmonary disease.
Does chronic obstructive pulmonary disease (COPD) severity increase atrial electromechanical delay and P-wave dispersion compared to healthy controls?

Does chronic obstructive pulmonary disease (COPD) severity increase atrial electromechanical delay and P-wave dispersion compared to healthy controls?
COPD severity is associated with increased P-wave dispersion and altered atrial electromechanical delay, which may serve as non-invasive markers for predicting atrial fibrillation risk in these patients.
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.

Çelik et al. (2021) conducted a cross-sectional in Chronic Obstructive Pulmonary Disease (COPD) (n=110). Chronic Obstructive Pulmonary Disease (COPD) vs. Healthy controls was evaluated on Interatrial electromechanical delay (EMD) (p=<0.001). Chronic obstructive pulmonary disease was associated with significantly decreased interatrial electromechanical delay (23.9 ms in severe COPD vs 29.5 ms in controls) and increased P-wave dispersion.
