&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Heart Rate Variability (HRV)&amp;#039;&amp;#039;&amp;#039; is the beat-to-beat variation in cardiac interval, controlled primarily by vagal autonomic tone. It is the most heavily validated single biomarker of autonomic-system flexibility and is the proposed primary proxy for ψ-field sensitivity in the [[Tho&amp;#039;ra Clan]]&amp;#039;s [[Psi-Tech]] line.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Mainstream physiology ==&lt;br /&gt;
&lt;br /&gt;
HRV is generated by the interplay between the parasympathetic (vagal) and sympathetic branches of the autonomic nervous system. Standard time-domain metrics:&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;RMSSD&amp;#039;&amp;#039;&amp;#039; — root mean square of successive differences; dominated by vagal tone.&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;SDNN&amp;#039;&amp;#039;&amp;#039; — standard deviation of NN intervals; overall variability.&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;pNN50&amp;#039;&amp;#039;&amp;#039; — fraction of intervals differing by &amp;gt; 50 ms; vagal correlate.&lt;br /&gt;
&lt;br /&gt;
Standard frequency-domain metrics:&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;HF (0.15–0.4 Hz)&amp;#039;&amp;#039;&amp;#039; — high-frequency, vagal-mediated.&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;LF (0.04–0.15 Hz)&amp;#039;&amp;#039;&amp;#039; — low-frequency, mixed sympathetic-vagal-baroreflex.&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;VLF (&amp;lt; 0.04 Hz)&amp;#039;&amp;#039;&amp;#039; — very-low-frequency, less understood; possible thermal / hormonal contribution.&lt;br /&gt;
&lt;br /&gt;
Established correlations: high HRV with cardiovascular health, emotional regulation, resilience, meditation practice. Low HRV with mortality risk, depression, chronic stress. These are mainstream cardiology (Task Force, 1996; Shaffer &amp;amp; Ginsberg, 2017).&lt;br /&gt;
&lt;br /&gt;
== The psi link ==&lt;br /&gt;
&lt;br /&gt;
The [[Psi Field]] framework predicts that ψ-field coupling is mediated by coherent neural / autonomic state. The vagus nerve is the body&amp;#039;s primary parasympathetic conduit and the substrate for [[Polyvagal Theory|Porges&amp;#039;s polyvagal]] account of social-engagement state. The hypothesis:&lt;br /&gt;
&lt;br /&gt;
# High resting HRV indexes autonomic flexibility, which is the prerequisite for the coherent state in which ψ coupling becomes measurable.&lt;br /&gt;
# Real-time HRV is the most field-deployable proxy for &amp;quot;operator coherence&amp;quot; the [[Psi Stabilizer]] and [[Psi Recorder]] can use.&lt;br /&gt;
&lt;br /&gt;
{{Psi-claim|status=TESTABLE|cites=Resonant Neurobiology, Intention as Psi Source}}&lt;br /&gt;
&lt;br /&gt;
A specific testable prediction: operators in a high-HRV state should show stronger effects on any future blinded ψ-task (e.g. retrocausal random-event-generator deviation per PEAR-style protocols) than the same operators in a low-HRV state. This prediction is unproven and remains pending Mk2 cohort data.&lt;br /&gt;
&lt;br /&gt;
== HeartMath grounding ==&lt;br /&gt;
&lt;br /&gt;
The HeartMath Institute has published replicable findings on &amp;#039;&amp;#039;&amp;#039;cardio-respiratory coherence&amp;#039;&amp;#039;&amp;#039; — a state where breath, heart rate, and blood pressure synchronise at ~0.1 Hz. Effect sizes on subjective wellbeing and cognitive performance are small but statistically replicable (McCraty et al., 2009). The wiki treats HeartMath as the empirical floor of the HRV-and-psi claim: &amp;#039;&amp;#039;&amp;#039;coherent HRV demonstrably improves wellbeing&amp;#039;&amp;#039;&amp;#039;; whether it also enables ψ-coupling is the speculative extension.&lt;br /&gt;
&lt;br /&gt;
== Measurement ==&lt;br /&gt;
&lt;br /&gt;
Field-deployable HRV requires a 1 kHz-sample PPG or ECG signal:&lt;br /&gt;
&lt;br /&gt;
* PPG: Polar H10 chest strap (~$90), Whoop, Empatica E4. Mainstream consumer-grade.&lt;br /&gt;
* ECG: medical Holter monitors; or open-source OpenBCI Cyton + ECG cape.&lt;br /&gt;
* Minimum recording: 5 minutes supine, paced breath at 6 breaths/min.&lt;br /&gt;
&lt;br /&gt;
The [[Psi Recorder]] and [[Psi Tether]] both use Polar H10 as the Mk1 reference part.&lt;br /&gt;
