Abstract：Objective To explore the application of ECG scatterplot in the early warning of malignant ventricular arrhythmia(MVA). Methods The characteristics of ECG scatterplot were comparatively analyzed before and after sudden death so as to know about its value in the early warning of MVA. Results Before sudden death of patients, the ECG scatterplot was characterized by short coupling interval ventricular premature beats(RonT ventricular premature beats), decreased heart rate variability, nonsustained ventricular tachycardia within QT boundary, ventricular parasystole(superwide QRS complex, which can be referred to through reversal technique), etc. Conclusion ECG scatterplot is a concise language for describing MVA; the features of its early warning information are obvious and easy to be recognized. The ECG scatterplot technique is suggested to be introduced into ECG monitoring system(including remote ECG monitoring) as soon as possible.
