The heart rate variability is defined as variation in distance between sequential ventricular complexes in the electrocardiogram and can be given in percent by referring the standard deviation to the average values of heart rate. The bivariate distribution of heart rate variability and of heart rate shows a discrimination of the group of comatose patients from brain dead subjects and normals.
心率变异性被定义为心电图中连续心室复合波之间距离的变化，通过将标准差与心率平均值相比较，可得出其百分比。心率变异性和心率的双变量分布显示，昏迷患者组与脑死亡受试者及正常人之间存在差异。
