HeartMath Limitations vs iTHRVE Progressive Developments

There are a couple of ‘mistakes’ or limitations that HeartMath has made regarding their measurement of the HRV (heart rate variability) and coherent breathing. HeartMath did not go as far as Dan Winter who developed the concept of coherent breathing and is a co-developer of iTHRVE apps. It seems that HeartMath stayed at the first step of their research which has some benefits, although limited.

SPECTRUM ANALYSIS
HearthMath is using one frequency as opposed to full spectrum of frequencies of iTHRVE app
With iTHRVE apps, we analyse all the frequencies of the spectrum as opposed to just one frequency as the HeartMath proposes. For example, if you compared it to an orchestra, what the HeartMath’s app is doing is analysing the quality of a small part of the whole orchestra ie just one musician or instrument, for example, the lead violinist. What is iTHRVE app doing is analysing the quality of the whole orchestra, all the instruments, all the musicians. So if some of the musician or instruments are out of tune – the whole concert won’t work – it will sound awful, no matter how good or in tune is the lead violinist or violin.

Coherence is not defined by how much one frequency is in phase regularity in the low frequencies of the heart (HRV). Imagine – if someone could play music with one tone at 6Hz, while other 100 tones above 20 Hertz were out of phase – it would sound horrible.

Immune health is optimal when the possible harmonics are working together nondestructively in the heart. It’s been demonstrated that harmonic inclusiveness in HRV (heart rate variability) predicts survival success of almost all chronic diseases.

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).

HRV and stress

Firstly – there is a primary measure of stress – related to change in long-term resting heart rate. Using the Polar chest strap- overnight HRV analysis with iTHRVE – is an ideal way to reveal – resting heart rate change – which is a primary useful indicator of stress:
