Recent experimental studies suggest that there is evidence for a synchronization between human heartbeat and respiration. We develop a physiologically plausible model for this cardiorespiratory synchronization, and numerically show that the model can exhibit stable synchronization against given perturbations. In our model, in addition to the well-known influence of respiration on heartbeat, the influence of heartbeat (and hence blood pressure) on respiration is also important for cardiorespiratory synchronization.
最近的实验研究表明，有证据显示人类心跳与呼吸之间存在同步性。我们针对这种心肺同步性建立了一个生理上合理的模型，并通过数值模拟表明该模型在面对给定扰动时能够展现出稳定的同步性。在我们的模型中，除了呼吸对心跳的众所周知的影响外，心跳（进而血压）对呼吸的影响对于心肺同步性也很重要。
