Abstract Objective To discuss the diagnostic value of remote monitoring technology combined with three dimensional ECG scatterplot technology forarrhythmia patients. Methods The 24-hour ambulatory electrocardiography(AECG) data(mass ECG data) of 32 arrhythmia patients were transmitted by remote network. With the Lorenz scatterplot analysis method of nonlinear theory, the intuitive geometric model was combined with mathematical model by the processing of computer, and the analysis software was translated into three dimensional model, before the occurrence time, duration, and frequency of arrhythmia could be extracted from longterm ECG data. Results Three dimensional colored ECG scatterplot was brightly colored, and possessed strong stereoscopic feel, which not only displayed the types and severity of arrhythmia intuitively, but also revealed its occurrence time, duration, and frequency. Conclusion Three dimensional ECG scatterplot is a new method of analyzing AECG quickly and accurately, which possesses both of the advantages of t -RR scatterplot and Lorenz scatterplot. Therefore, it is applicable to the clinical diagnosis of arrhythmia.
