摘要

背景:慢性心房颤动(CAF)会诱发各种电活动紊乱,单个突变可导致多种表型或组合。确定与电活动紊乱相对应的心电图变化与右心室收缩功能(RVSF)的相关性,对 CAF 的治疗和预后非常重要。因此,本研究探讨了 CAF 患者心电图变化与 RVSF 的相关性。研究方法2022年3月至2023年3月,对我院心内科收治的97例CAF患者(研究组)和100例接受健康检查的正常人(对照组)进行超声心动图和心电图检查,记录相关参数,进行相关性分析。结果:两组的心电图指标和右心功能参数存在显著差异。研究组的心率、QTc间期、QT间期和T波时间明显高于对照组(P<0.05)。研究组的右心室舒张末期容积(RVEDV)和右心室收缩末期容积(RVESV)明显高于对照组,而右心室搏出量(RVSV)和右心室射血分数(RVEF)则低于对照组(P<0.05)。皮尔逊相关分析显示,QTc间期、QT间期和T波时间与RVESV呈正相关(P<0.05);QTc间期、QT间期和T波时间与RVSV呈负相关(P<0.05);QTc间期与RVEF呈负相关(P<0.05)。结论CAF 患者的心电图变化与 RVSF 之间存在相关性。

Correlation between Electrocardiogram Changes and Right Ventricular Systolic Function in Patients with Chronic Atrial Fibrillation
Background: Chronic atrial fibrillation (CAF) induces various electric disturbances, and a single mutation can cause multifarious phenotypes or combinations. Identifying the correlation of electrocardiogram changes corresponding to the disorders of electrical activity with right ventricular systolic function (RVSF) is important for the treatment and prognosis of CAF. Therefore, this study explored the correlation of electrocardiogram changes and RVSF in patients with CAF. Methods: From March 2022, to March 2023, 97 patients with CAF admitted to the Department of Cardiology of our hospital (study group) and 100 normal people who received health examination (control group) were subjected to echocardiogram and electrocardiogram to record relevant parameters for correlation analysis. Results: Significant differences were found in the electrocardiogram indices and right heart function parameters between the two groups. The study group had significantly higher heart rate, QTc interval, QT interval and T wave time than the control group (p < 0.05). The study group showed significantly higher right ventricular end-diastolic volume (RVEDV) and right ventricular end-systolic volume (RVESV), and lower right ventricular stroke volume (RVSV) and right ventricular ejection fraction (RVEF) than the control group (p < 0.05). Pearson correlation analysis showed that QTc interval, QT interval, and T wave time were positively correlated with RVESV (p < 0.05); QTc interval, QT interval, and T wave time were negatively correlated with RVSV (p < 0.05); and QTc interval was negatively correlated with RVEF (p < 0.05). Conclusion: A correlation exists between electrocardiogram changes and RVSF in patients with CAF.
