Article Synopsis
- Frequency-domain indices of heart rate variability (HRV) traditionally evaluate sympathovagal balance but can be affected by individual differences and breathing variations.
- The study proposes a new method called ECG-derived respiration with variable frequency complex demodulation (EDR-VFCDM) to analyze HRV by focusing on respiratory sinus arrhythmia (RSA) linked to breathing frequency.
- EDR-VFCDM outperformed traditional HRV analyses in detecting cognitive stress across different groups and tasks, proving to be more reliable for assessing how mental demands fluctuate, especially in athletes and individuals with respiratory issues.
