我们研究了心率和血压的低频振荡之间的同步性，人类的基本频率接近0.1赫兹。提出了一种基于振荡相同步相对时间的定量估计振荡过程间同步的方法。结果表明，与急性心肌梗死患者相比，健康受试者心率和血压的低频振荡之间的内部同步期平均要长得多。
We investigate synchronization between the low-frequency oscillations of heart rate and blood pressure having in humans a basic frequency close to 0.1 Hz. A method is proposed for quantitative estimation of synchronization between these oscillating processes based on calculation of relative time of phase synchronization of oscillations. It is shown that healthy subjects exhibit on average substantially longer epochs of internal synchronization between the low-frequency oscillations in heart rate and blood pressure than patients after acute myocardial infarction.
