Abstract：This paper investigates the application value of scatter point drifting method in the rapid analysis of atrial pararrhythmia without atrial premature beats (APB) being conducted down, and establishes a foundation for rapidly analyzing related ambulatory electrocardiography. We selected typical cases of atrial pararrhythmia without frequent APB being conducted down, and arhythmia cases including atrial pararrhythmia complicated by paired APB individually conducted down. The characteristics of their ECG scatter plots were analyzed combined with the scatter point drifting method, and the analysis skills were summarized. There is an analogy between the characteristic point set related to long period due to unconducted down APB and the homonymous one without long period. The former is equivalent to a drift from the latter. The drifting law of Lorenz scatter plot is as follows:
with extended front periods, the characteristic point set moves to the right; with extended back periods, the characteristic point set moves upwards; with extended front and back periods, the characteristic point set moves to the upper right.
The drifting law of the difference scatter plot is as follows:
with extended front periods, the characteristic point set moves to the left; with extended back periods, the characteristic point set moves upwards; with extended middle periods, the characteristic point set moves to the bottom right.
The appearance of long period complicates the original scatter plot of arrhythmia, and the scatter point drifting method serves as a “secret weapon” to
