Abstract The ambulatory electrocardiography(AECG) of sinus rhythm complicating atrial parasystolic rhythm and frequent premature ventricular
contraction is relatively complex. It is almost impossible to analyze it accurately and quickly without the help of ECG scatterplot. The tRR scatterplot
can show the occurring time and duration of arrhythmia; Lorenz scatterplot can reflect electrophysiological characteristics of dominant rhythm and auxiliary
rhythm respectively; difference scatterplot can clearly reveal the overlapping and illegible rhythm information in Lorenz scatterplot. The three kinds of
scatterplots make complementation and confirmation mutually, depicting the competition and interfering process of sinus rhythm complicating atrial
parasystolic rhythm and frequent premature ventricular contraction by multiple perspectives. It is helpful to analyze AECG accurately and quickly,and
comprehend the electrophysiological significance of arrhythmia further, if clinicians can master the simple and effective analysis method of ECG scatterplot.
