心电散点图(RR-Lorenz图)中的每一个散点表示相邻的两次心脏搏动的周期长度,其大小分别对应于二维坐标系中的横、纵轴值。心脏有其固有的电生理特性,此特性决定了两个相邻心脏搏动的周期长度,不论是正常的搏动,还是异常的搏动,还是异常和正常搏动的组合,都在心脏自主调节的能力以内,否 Each scatter in the ECG scatter plot (RR-Lorenz plot) represents the length of the cycle of two adjacent cardiac beats, the magnitude of which corresponds to the horizontal and vertical axis values ​​in the two-dimensional coordinate system, respectively. The heart has its own electrophysiological properties which determine the length of the cycle of two adjacent cardiac beats, whether normal beats or abnormal beats, or a combination of abnormalities and normal beats, all within the capacity of the heart to autonomously regulate ,no
