〔Abstract〕Objective To explore the application effect of electrocardiogram CE(G) examination in patients with severe eclampsia. Methods A total of 60 patients with severe eclampsia treated in Jingdezhen Maternal and Child Health Hospital from March 2020 to March 2021 were selected as the observation group, and 60 healthy pregnant women in Jingdezhen Maternal and Child Health Hospital were selected as the control group. The subjects of the two groups were given ECG examination, and the detection rates of electrocardiogram abnormalities (ventricular tachycardia, sinus arrhythmia, ventricular extrasystole, T wave change, low voltage, prolonged Q-T interval, atrial extrasystole, short P-R interval and left deviation of electrical axis) before the two groups were compared, according to the electrocardiogram results, the observation group was given spasmolysis, sedation and other treatment, and then the detection rate of abnormal electrocardiogram in the two groups after 1 week, as well as the incidence of adverse maternal and infant outcomes after delivery (placental abruption, postpartum hemorrhage, neonatal asphyxia, premature delivery, cesarean section) were compared. Results Before entering the group, the abnormal detection rate of electrocardiogram in the observation group was higher than that in the control group, and the difference was statistically significant (P < 0.05); One week after entering the group, there was no significant difference in the detection rate of electrocardiogram abnormalities between the two groups (P > 0.05); There was no significant difference in the incidence of adverse maternal and infant outcomes between the two groups (P > 0.05). Conclusion Through the continuous monitoring of electrocardiogram, the abnormal changes of electrocardiogram in patients with severe eclampsia can be timely understood, and targeted treatment can be given to effectively reduce blood pressure and heart rate of patients, correct abnormal electrocardiogram, and improve pregnancy outcomes.
