摘要
本文提出用Ｘ－Ｒ－Ｘ间期排列法作相关性预测图，可预测是否为调频性并行心律（ＭＰ）。此图左侧各点代表Ｘ－Ｒ间期，右侧各点代表Ｒ－Ｘ间期。ＭＰ时，两侧各点皆从右上向左下呈斜线分布，右侧斜线常有一明显中断，该处相当于双相反应曲线的逆转点。此时，若Ｒ－Ｘ与Ｘ－Ｒ－Ｘ间期的相关系数为正值，且Ｐ＜０．０１，可确诊为ＭＰ；若Ｐ＞０．０１，但＜０．０５，可提示诊断为ＭＰ。
The paper suggests that by making use of a calculated chart of correl-ativity with the X-R-X in tervals , it may determine whether the modulated parasystole(MP) is present or not. The points in the right side of the chart were the R-X intervalsand the X-R intervals in the left side. During MP. it was shown that points on each sideof the chart were distributed in a oblique line form. A break point in the right obliqueline commonly appeared. it would be equivalent to the reversal point of the biphasicphase-response curve. Now, if the correlation coefficient(r) between the R-X intervalsand the X-R-X intervals is positive value and P<0. 01 . it would be a definite diagnosisof MP; if the value is P>0. 01 but P<0. 05, it may be a suggestive diagnosis of MP.
