Ordinal patterns with ties and tolerance provide a physiology-driven method to quantify cardiorespiratory interactions

We propose a new analytical approach based on ordinal pattern analysis to investigate respiratory heart rate variability (RespHRV, also called respiratory sinus arrhythmia), specifically modulation of heart rate across different phases of the respiratory cycle. The method uses RR...
