(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.  </span> <b style="font-size:.9em;"> <span lang="en-us" style="font-size:10pt;line-height:200%;font-family:Arial, sans-serif;" xml:lang="en-us">Results:  </span> </b> <span lang="en-us" style="font-size:10pt;line-height:200%;font-family:Arial, sans-serif;" xml:lang="en-us">The mean age of the study population was </span> <span lang="en-us" style="font-size:10pt;line-height:200%;font-family:Arial, sans-serif;" xml:lang="en-us">27.70 ± 5.62 and mean gestational week was 7.37 ± 1.55. </span> <span lang="en-us" style="font-size:10pt;line-height:200%;font-family:Arial, sans-serif;" xml:lang="en-us">Parity in f-QRS positive group was higher than in control group (p=0.01). There was a statistically significant trend between fragmentation frequency and parity number (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  </span> <b style="font-size:.9em;"> <span lang="en-us" style="font-size:10pt;line-height:200%;font-family:Arial, sans-serif;" xml:lang="en-us">Conclusions:   </span> </b> <span style="font-family:Arial, sans-serif;font-size:10pt;">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. </span> </p>}, number={1}, publisher={Sakarya University}
