- •
Decoupling heart rate variability from its respiration driven part could deliver new information.
- •
Coupling between heart rate variability and respiration is quantified using Granger's causality.
- •
Decoupling is then performed with a linear filter.
- •
The procedure was developed using synthetic signals and tested on real recordings.
- •
Natural breathing and paced respiration were analyzed prior and after decoupling.
