Abstract :Objective:  The aim of this study was to investigate the relationship between the presence of fragmented QRS insert ignore into journalissuearticles values(f-QRS); complex on electrocardiography insert ignore into journalissuearticles values(ECG); and maternal demographic characteristics and left ventricular systolic and diastolic dysfunction on echocardiography.  Materials and Methods:  473 pregnant women enrolled in this study and divided into two groups. insert ignore into journalissuearticles values(f-QRS positive group n=77, f-QRS negative group n=396 );. Maternal demographic features and echocardiographic parameters of all participants were recorded and compared between two groups.  Results:  The mean age of the study population was 27.70 ± 5.62 and mean gestational week was 7.37 ± 1.55. Parity in f-QRS positive group was higher than in control group insert ignore into journalissuearticles values(p=0.01);. There was a statistically significant trend between fragmentation frequency and parity number insert ignore into journalissuearticles values(p=0.002);. There were no significant differences between two groups in terms of age, gestational week, heart rate, body mass index. Left ventricle end-systolic and diastolic diameters and left ventricular ejection fraction were similar between the two groups  Conclusions:   The presence of f-QRS was correlated with increase in number of parity and we suggest that multiparity may be a risk factor for cardiac events during pregnancy. Pregnant women with f-QRS on their rest ECG need extra attention in terms of cardiovascular disease. By demonstrating clinical significance of f-QRS, this simple tool might be used to determine women who could be at risk for developing cardiac dysfunction in pregnancy.
