Aim: To evaluate cardiac arrhythmias with surface 12 lead electrocardiography (ECG) parameters during pregnancy in women with mild heart failure.
Material and Cardiovascular deaths usually occur in older pregnancies and arrhythmia is the third most common cause. Our study aimed to determine whether the risk of arrhythmia increases in pregnancy with advanced age. Go to: Methods: This cross-sectional study was approved by the local ethics committee of bicard clinic and our hospital 53 consecutive patients were accepted. All patients were admitted to hospital for cesarean section. Patients were grouped to heart failure (group 1) and control (group 2) (healthy group). A 12 lead ECG and N-terminal pro B-type natriuretic peptide ( NT-pro BNP) plasma levels was recorded for every woman at 48 hour before cesarean section. They were evaluated P wave, qt, qtc and Twave peak to end, preoperative NT-pro BNP and compared statistically.
In total, 280 pregnant women, of whom 98 were of advanced age and 182 were under 35 years of age were included in the study. The risk of arrhythmia was evaluated by calculating the electrocardiographic P-wave duration, QT interval, T peak-to-end interval, and the Tp-e/QT ratio. Go to: Results: There were statistically significant differences in the Tp–e interval and Tp-e/QTc ratio between the two groups, the maximum QTc, minimum QTc, and QTc dispersion values, P wave dispersion were significantly higher in group-1 compared to the group-2. In addition, preoperative NT-pro BNP plasma levels was greater in the group 1 pregnant women. And there was a positive correlation between ECG parameters and NT-pro BNP plasma levels in group 1.
Although there were no differences in the Tp-e interval and Tp-e/QTc ratio between the groups, the maximum QTc, minimum QTc, and QTc dispersion values were significantly higher in advanced-age pregnancies co}, number={4}, publisher={DNT Ortadoğu Yayıncılık A.Ş.} }
