心电散点图在心律失常快速诊断中的应用

The application of electrocardiology scatterplot chart in the rapid diagnosis of arrhythmia

目的通过与诊断结果对比观察,探讨心电散点图在快速诊断心律失常方面的临床应用价值。方法应用动态心电图记录仪记录患者连续24h心电信号,利用计算机自动检测技术,进行心电分析,并同步绘制24h心电散点图。将诊断结果分为窦性心律、室上性早搏、室性早搏、心房颤动、差异性传导5组,分别将4组心律失常结果与心电散点图检测的诊断结果进行对照,计算出二者的符合率及各组的B线斜率,进行分析对比。结果室上性早搏组与室性早搏、心房颤动、差传组差异显著(p<0.001);室性早搏组与室上性早搏、心房颤动、差传组差异显著(p<0.001);心房颤动组与差传组差异不显著(p>0.05)。结论心电散点图在长程大样本心电数据中,快速诊断心律失常,尤其是室上性早搏、室性早搏、心房颤动等时具有较好的临床应用价值。

Objective Through comparing the result with diagnosis ECG observation, explore ECG scatterplot chart in rapid diagnosis arrhythmia. Methods Application recorder detection of patients with continuous recording 24 hours of ECG signals, using computer automatic detection technology ECG analysis, and synchronous ECG drawing 24 hours scatterplot chart diagnosis will be divided into sinus rhythm, supraventricular premature beats, premature ventricular contractions, atrial fibrillation, intraventricular aberrant conduction,5 groups. Respectively 4 groups arrhythmia results with the ECG scatterplot chart detection diagnosis comparison, calculate both accuracy and group B line slope, with statistical methods are analyzed. Results With variance analysis（One-Way ANOVA） and LSD test or Dunnett-c test for binary comparison, supraventricular premature group and premature ventricular contractions, atrial fibrillation, intraventricular aberrant conduction, significant differences（p〈0.001）; ventricular premature beats and supraventricular premature beats group, atrial fibrillation, intraventricular aberrant conduction, significant differences（p〈0.001）; atrial fibrillation group and intraventricular aberrant conduction groups was not significant（p〉0.05）. Conclusions ECG scatterplot chart of the long-range large sample ECG data in rapid diagnosis arrhythmia, especially supraventricular premature beat, ventricular premature beat, atrial fibrillation, etc. has good value of clinical applications.
