散点图与24 h动态心电图诊断心律失常的价值分析

Value Analysis of Scatter Plot and 24-Hour Ambulatory ECG for Arrhythmias

目的分析心律失常患者采取散点图和24 h动态心电图进行诊断的临床价值。方法选择2020年8月—2022年8月黑龙江省第二医院收治的心律失常90例患者作为研究组,选择同期到黑龙江省第二医院进行健康体检人员90例作为对照组。两组均给予24 h动态心电图进行诊断,且通过散点图形式绘制检查的结果,对比分析24 h动态心电图、散点图的诊断情况。结果经研究组包括心率减速力(deceleration capacity of rate,DC)、24 h内每5分钟节段窦性R-R周期平均值的标准差(standard deviation of the mean of sinus R-R cycles every 5min over 24 h,SDANN)、相邻正常心动周期差值的均方根(root mean square of adjacent normal cardiac cycle differences,rMSSD)、24 h窦性心搏间期标准差(24-hour standard deviation between sinus beats,SDNN)均低于对照组,差异有统计学意义(P<0.05)。研究组散点图的形态复杂状、彗星状和扇形状比例高于对照组,差异有统计学意义(P<0.05)。研究组散点图为彗星状、鱼雷状、复杂状患者心率变异性(heart rate variability,HRV)正常范围为92.31%、70.00%、67.50%。研究组患者疾病诊断的准确性为97.78%,高于对照组的3.33%,差异有统计学意义(P<0.05)。结论心律失常患者采取散点图和24 h动态心电图进行诊断的临床价值较高,散点图可作为有效的参考依据,可提升患者疾病诊断的准确性,临床上值得推广使用。

Objective To analyze the clinical value of using scatter plots and 24-hour holter for diagnosis in patients with arrhythmias.Methods From August 2020 to August 2022,a total of 90 patients with arrhythmia admitted to the Second Hospital of Heilongjiang Province were selected as the research group,and 90 patients who came to the Second Hospital of Heilongjiang Province for health examination during the same period were selected as the control group,and 24-hour holter was given to both groups for diagnosis,and the results of the examination were plotted in the form of scatter plot,and the diagnosis of 24-hour holter and scatter plot was compared and analyzed.Results After testing,deceleration capacity of rate(DC),standard deviation of the mean of sinus R-R cycles every 5 min over 24 h(SDANN),root mean square of adjacent normal cardiac cycle differences(rMSSD),24-hour standard deviation between sinus beats(SDNN)in the study group were lower than those in the control group,and the differences were statistically significant(P<0.05).The proportion of morphological complexity,comet-like and fan-shaped scatter plots in the study group was higher than that in the control group,and the differences were statistically significant(P<0.05).The scatter plots of the study group showed comet-shaped,torpedo-like and complex patients,and the normal range of heart rate variability(HRV)was 92.31%,70.00%,and 67.50%.The accuracy of disease diagnosis in the study group was 97.78%higher than that in the control group of 3.33%,and the difference comparison was statistically significant(P<0.05).Conclusion The clinical value of scatter plot and 24-hour ambulatory electrocardiogram for diagnosis in patients with arrhythmia is high,and the scatter plot can be used as an effective reference to improve the accuracy of disease diagnosis of patients,which is worthy of clinical use.
