Beat-to-beat variations in heart period provide information on cardiovascular control and are closely linked to variations in arterial pressure and respiration. Joint symbolic analysis of heart period, systolic arterial pressure and respiration allows for a simple description of their shared short-term dynamics that are governed by cardiac baroreflex control and cardiorespiratory coupling. In this review, we discuss methodology and research applications. Studies suggest that analysis of joint symbolic dynamics provides a powerful tool for identifying physiological and pathophysiological changes in cardiovascular and cardiorespiratory control.
心跳周期的逐搏变化提供了心血管控制方面的信息，并且与动脉血压和呼吸的变化密切相关。对心跳周期、收缩期动脉血压和呼吸进行联合符号分析，可以简单描述它们由心脏压力反射控制和心肺耦合所支配的共同短期动态变化。在这篇综述中，我们讨论了方法和研究应用。研究表明，联合符号动力学分析为识别心血管和心肺控制中的生理和病理生理变化提供了一个强大的工具。
