Abstract With deepening understanding of the graphic mechanism of Lorenz plot, the related concepts and terminologies have been increasing rapidly and their connotations require to be expounded. This paper focuses on explaining several common clinical concepts at present, including RR interval difference Lorenz plot, tRR scatterplot, electrocardioattractor, big data, “two ends, two lines, and eight regions”, “four diagnostic essentials” for arrhythmia (number of subgraphs, graphic shapes, locations of graphs, and B linear slope), preceding point of premature beat, main point of premature beat, following point of premature beat, preceding block point, following block point, homogeneous attractors with the same origin, homogeneous attractors with different origins, etc.
