Assessment of atrial conduction time and P-wave dispersion in patients
with gestational diabetes mellitus
Abstract
Purpose: We aimed to assess atrial conduction time and P wave
dispersion in Gestational Diabetes Mellitus (GDM) patients.
Methods: 30 patients with GDM and 30 healthy pregnant women
were included to the study. Atrial conduction time times (PA) were
calculated by the time interval from the onset of the P wave on the
electrocardiography (ECG) to the onset of the late diastolic flow (Am
wave) on echocardiography; from the lateral mitral annulus (PA lateral),
septal mitral annulus (PA septum), and right ventricular tricuspid
annulus (PA tricuspid). Results: Mean PWD were higher in GDM
(52.7±5.1 ms vs. 28.9±4.2 ms, p<0.001). PA lateral, PA septal
and PA tricuspid were significantly higher in the GDM patients compared
to the control group (65.7±4.2ms vs. 47.7±4.7 ms, p<0.001;
56.1±3.4 ms vs. 40.8±3.7 ms, p<0.001 and 48.4±3.9 ms vs.
36.0±3.6 ms, p<0.001 respectively). Conclusion: We
suggest that patients with GDM has higher PWD and higher atrial
conduction and EMD times compared to otherwise healthy pregnant control
group.
