Heart coherence. Coherent breathing. How to measure heart and breath coherence with HRV app?
With iTHRVE – you have the latest science in the measurement of heart coherence. We display a simpified (and limited – see below ) – single harmonic version of heart coherence measure – AND in addition – we display the far more sophisticated and healthy harmonic inclusive – FULL SPECTRUM COHERENCE (3rd order power spectra- see below).
Below – in green and – see the third order power spectra (or FFT3) – graph of coherence in the HRV- as plotted by iTHRVE. Note we plot both that graph derived directly from the HRV peak – and separately derived from the wave of blood pressure change – which iTHRVE is able to separately measure and graph (see discussion also in Stress Measue with iTHRVE).
