Abstract

Objective
To explore the diagnostic value of electrocardiograph scatter plot and routine electrocardiogram in arrhythmia.
Methods
A total of 950 patients who received electrocardiogram for suspected arrhythmia were selected as subjects. All patients underwent routine electrocardiogram and electrocardiogram scatter plot examination, and the slope of rates electrocardiogram scatter plot B line in patients with different types of arrhythmia were analyzed. Receiver operating characteristic (ROC) curve was used to analyze the efficiency of B-line slope in diagnosing different types of arrhythmia and the efficiency of conventional electrocardiogram combined with electrocardiogram scatter plot.
Results
The diagnostic accuracy of routine electrocardiogram was 73.78%(622/843); the diagnostic accuracy of electrocardiogram scatter plot was 85.88%(724/843); the diagnostic accuracy of conventional electrocardiogram combined with electrocardiogram scatter plot was 96.56%(814/843). ROC curve analysis showed that the area under the curve (AUC) of electrocardiogram scatter plot slope for diagnosis of superventricular premature beat, atrial fibrillation, indoor differential conduction and ventricular premature beat were 0.951, 0.614, 0.675 and 0.961, respectively. The AUC of routine electrocardiogram, electrocardiogram scatter diagram and their combination for the diagnosis of arrhythmia were 0.729, 0.827 and 0.936, respectively.
Conclusion
Electrocardiogram scatter plot can diagnose arrhythmia quickly, its combination with routine electrocardiogram diagnosis can better reduce the rate of missed diagnosis.
- electrocardiogram scatter plot,
- routine electrocardiogram,
- arrhythmia,
- missed diagnosis
