摘　　要：目的探讨心电散点图对常见心律失常的诊断价值。方法分析如皋市人民医院2016年7月至2018年6月心内科门诊和住院部诊治的心律失常患者100例的临床资料,患者均行动态心电图检查,应用t-RR散点图分析诊断心律失常,对比动态心电图和心电散点图诊断结果,分析心电散点图诊断心律失常的效能。结果心电散点图诊断室上性早搏22例,室性早搏18例,心房颤动(以下简称房颤)14例,心房扑动(以下简称房扑)15例,房颤伴室性早搏8例,房颤伴室内差异性传导7例,房颤合并房扑5例,诊断正确89例,总符合率89.00%。室上性早搏散点图B线斜率(0.45±0.13),在各类型心律失常中最大,室性早搏最小为(0.08±0.03),室上性早搏、室性早搏B线斜率与其它各组比较,差异均有统计学意义(F=5.031,P<0.05),房颤、房扑、房颤伴室性早搏、房颤伴室内差异性传导、房颤合并房扑组之间B线斜率比较,差异无统计学意义(P>0.05)。心电散点图诊断心律失常的灵敏度、特异度、准确度为82.05%、90.51%、92.57%,曲线下面积为0.833(95%CI0.271~0.942)。结论心电散点图在诊断心律失常方面具有较高的应用价值,可实现复杂心律失常的准确诊断。Objective To explore the diagnostic value of electrocardiogram(ECG)in common arrhythmias,and to provide an effective reference for clinical diagnosis of arrhythmias.Methods The clinical data of 100 arrhythmia patients in the Department of Cardiology of Rugao People's Hospital from July 2016 to June 2018 were analyzed.All the patients were examined by dynamic ECG.The t-RR scatter plot was used to diagnose arrhythmia,and the diagnosis results were compared between the dynamic ECG and ECG scatter plot.The efficacy of ECG scatter plot in the diagnosis of arrhythmia was analyzed.Results By ECG scatter plot,22 cases of premature beat,18 cases of ventricular premature beat,14 cases of atrial fibrillation,15 cases of atrial flutter,8 cases of atrial fibrillation with ventricular early,7 cases of atrial fibrillation with indoor differential transmission,5 cases of atrial fibrillation combined with atrial flutter,89 cases of correct diagnosis,and the total coincidence rate was 89.00%.The B line slope of the supraventricular premature beat point map was(0.45±0.13),which was the largest in each type of arrhythmia,and the minimum ventricular premature beat was(0.08±0.03).The difference in the slope of the supraventricular premature beat and the ventricular premature beat B line was statistically significant(F=5.031,P<0.05).The atrial fibrillation,atrial flutter,atrial fibrillation and ventricular early,atrial fibrillation accompanied with indoor had no statistically significant differences in the slope of B line(all P>0.05).The sensitivity,specificity and accuracy of ECG in the diagnosis of arrhythmia were 82.05%,90.51%,92.57%,respectively,and the area under the curve was 0.833(95%CI:0.271-0.942).Conclusion ECG scatter plot has a high application value in the diagnosis of arrhythmias,and can realize the accurate diagnosis of complex arrhythmias.
