Objective To investigate the value of ECG scatter plots in the rapid diagnosis of arrhythmia. Methods A retrospective analysis was performed for 200 patients who were treated in our hospital from January 2023 to July 2024, and all patients received examinations with ECG scatter plots and routine electrocardiography. The diagnostic value of ECG scatter plots and routine electrocardiography was compared. Results Among the 200 patients, 178 had a confirmed diagnosis based on comprehensive clinical assessment. Compared with routine electrocardiography, ECG scatter plots had a significantly higher accuracy rate in the diagnosis of various types of arrhythmia, and the combination of the two diagnostic methods had a significantly higher accuracy rate than each method alone (P<0.05). There was a poor consistency in the accuracy rate of routine electrocardiography in the diagnosis of arrhythmia (Kappa=0.260), while ECG scatter plots had a fairly good consistency (Kappa=0.470), and the combination of the two methods had a good consistency (Kappa=0.810). ECG scatter plots had a significantly higher diagnostic accuracy rate than routine electrocardiography, and the combination of the two methods had a significantly higher diagnostic accuracy rate than each method used alone (P<0.05). There were also significant differences in the B-line slopes of ventricular premature beats, supraventricular premature beats, and atrial fibrillation (P<0.05). Conclusion ECG scatter plots have a significantly higher accuracy rate than routine electrocardiography in the diagnosis of arrhythmia, and the combination of the two methods can further improve diagnostic efficacy, which provides a reliable basis for clinical diagnosis and treatment.

Objective To observe the effects of NNN-linked health management based on health empowerment in patients with preeclampsia. Methods A total of 68 preeclampsia patients admitted to Xiamen Fifth Hospital between January 2021 and January 2024 were selected as the study subjects. They were divided into two groups using the random number table method. The control group (n=34) received routine nursing care, while the observation group (n=34) received health empowerment-based NNN-linkage health management. Maternal outcomes, fetal or newborn outcomes, self-care ability, and nursing satisfaction were compared between the two groups. Results The natural delivery rate and cesarean section rate in the observation group were 55.88% (19/34) and 44.12% (15/34), respectively, while those in the control group were 26.47% (9/34) and 70.59% (24/34), respectively. The natural delivery rate in the observation group was higher than that in the control group, while the cesarean section rate was lower than that in the control group, and the differences were statistically significant (χ²=6.071, 4.870, P<0.05). The incidence of obstetric complications was 14.71% (5/34) in the observation group and 38.24% (13/34) in the control group, with the observation group showing a significantly lower incidence (χ²=4.836, P<0.05). The incidence of adverse outcomes in fetuses or newborns was 17.65% (6/34) in the observation group and 41.18% (14/34) in the control group, with the observation group showing a significantly lower incidence (χ²=4.533, P<0.05). The total scores of the Exercise of Self-Care Agency Scale for the observation group and the control group after intervention were (140.62±10.41) points and (129.57±9.34) points, respectively, with the observation group showing a significantly higher score than the control group (t=4.607, P<0.05). The nursing satisfaction rates of the observation group and the control group were 94.12% (32/34) and 76.47% (26/34), respectively, with a statistically significant difference (χ²=4.221, P<0.05). Conclusion For patients with preeclampsia, the NNN-linked health management based on health empowerment improves maternal and infant outcomes, enhances their self-care ability, and increases nursing satisfaction.
