Resonance is a measure of the phase relationship between the breathing induced Valsalva Wave and the heart rate variability cycle it induces. It is indicated by the "Coherence Curve" which approaches -1 as the phase alignment nears 180 degrees. The Coherence Curve is the correlation coefficient of the two phenomena. In theory the Coherence Curve can never be -1 because the heart rate variability cycle (blue) is an autonomic outcome of the Valsalva Wave (red), and must therefore lag slightly behind the Valsalva Wave. However, as described in Personal Resonance Protocol, it is possible to sustain -.98 for 5 minutes or longer.
The yellow line in the lower panel is a threshold that is settable in .05 increments so one is able to set it at their personal best. To discover one's personal resonant frequency, it is recommended that one realize and sustain a Coherence Curve below -.8 and record it for 5 minutes. Then post process the record to find the frequency that produced the resonance. This is explained in detail in Personal Resonance Protocol including performing Fourier analysis using Excel to discover one's personal resonant frequency.
The "Resonance Simul" Screen (Simultaneous Valsalva Wave & HRV)
Resonance can be realized by breathing in synchrony with the first order biometric, the Valsalva Wave inhaling at peaks and exhaling at valleys.
The "Resonance Valsalva Wave" Screen
Or, resonance can be realized by breathing in synchrony with the heart rate variability (HRV) cycle, the 2nd order biometric, exhaling at peaks and inhaling at valleys, the opposite method relative to Valsalva Wave biofeedback.
