通过测量一系列 50 个正常[男性][男性]的脉搏间隔来预测心电图心室复合波持续时间（Q-T 时间）的最准确公式为：Q-T=.1536 R-R + .2462，对于 54 个正常[女性][女性]，Q-T = .1259 R-R+.2789，其中 Q-T=心电图持续时间收缩期，R-R=脉搏间隔。使用年龄、高度和重量。个体的差异、心电图的轴和 T 波高度并不能明显提高心电图心室复合波持续时间的预测准确性。其他工作人员发现，心电图心室复合波的持续时间相对于相应的脉搏率更短。造成这种差异的原因尚不清楚。
The most accurate formulas for the prediction of the duration of the electro-cardiographic ventricular complex (Q-T time) from measurements of pulse interval in a series of 50 normal [male][male] are: Q-T=.1536 R-R + .2462, and for 54 normal [female][female], Q-T = .1259 R-R+.2789 in which Q-T=duration of electrocardiographic systole, and R-R=pulse interval. The use of age, ht., and wt. of the individual, and axis and T-wave height of the electrocardiogram does not appreciably increase the accuracy of prediction of the duration of the electrocardiographic ventricular complex. Other workers have found the duration of the electrocardiographic ventricular complex to be shorter for corresponding pulse rates. The reason for this difference is not apparent.
