Until recently, it had not been recognized that predictions regarding the number of sinus beats interposed between two consecutive parasystolic beats could be made. In a case of perfect, pure parasystole resulting from unintentional fixed rate ventricular pacing, the following was observed: there were consistently three different values (0,2,3) for the number of interposed sinus beats; only one of these values was odd, and the sum of the two smaller values was one less than the larger value. Our findings, which are in keeping with those obtained in an mathematical model, may be of additional help in the diagnosis of this elusive arrhythmia.
直到最近，人们才认识到可以对两个连续并行心律心搏之间的窦性心搏数量进行预测。在一例因无意的固定频率心室起搏导致的完美、纯并行心律病例中，观察到以下情况：窦性心搏的插入数量始终有三个不同的值（0、2、3）；这些值中只有一个是奇数，且两个较小值的和比最大值小1。我们的发现与数学模型中获得的发现一致，可能对诊断这种难以捉摸的心律失常有额外帮助。
