Key result
Phase-averaged characterization of respiratory sinus arrhythmia revealed a phase lag difference of 11.4 +/- 8.5% (P < 0.004) between supine and standing postures in healthy young adults.
Observational (n=25)
Mean Difference: 11.4
p-value: p=< 0.004
A novel phase-averaged method for characterizing respiratory sinus arrhythmia patterns demonstrates individual stability over time and sensitivity to postural changes, potentially serving as a long-term index for cardiorespiratory coupling.

Postural RSA phase shifts merit inclusion in autonomic research protocols; leaves open validation as a stable individual coupling index.
Gilad et al. (2004) conducted an observational in Healthy (n=25). Phase-averaged characterization of respiratory sinus arrhythmia pattern vs. Supine vs standing postures was evaluated on Phase lag difference between supine and standing postures (Mean difference 11.4%, p=< 0.004). Phase-averaged characterization of respiratory sinus arrhythmia revealed a phase lag difference of 11.4 +/- 8.5% (P < 0.004) between supine and standing postures in healthy young adults.
