Stress and Tinnitus; Transcutaneous Auricular Vagal Nerve Stimulation Attenuates Tinnitus-Triggered Stress Reaction

Study from Helsinki on 171 patients.  (Impressive! Especially given Finland’s small size.) It has a measure I’ve never seen before. ie. “HRV age”.  Apparently the TAVNS decreased the patients’ HRV age by 9 years. Full article here. Front Psychol . 2020 Sep 17;11:570196. doi: 10.3389/fpsyg.2020.570196. eCollection 2020. Stress and Tinnitus; Transcutaneous Auricular Vagal Nerve Stimulation…

Effect of Yoga Therapy on Disease Activity, Inflammatory Markers, and Heart Rate Variability in Patients with Rheumatoid Arthritis

This article looks at two aspects of treatment and health that I’m deeply interested in.  One is the autonomic nervous system and HRV specifically.  The other is the immune system and inflammatory markers.  Acupuncture, also, affects inflammatory markers and HRV, as attentive readers of this blog know! Yoga for inflammation and HRV 6.15.2020 The Journal…

Spectral Analysis of Heart Rate Variability During Trigger-Point Acupuncture of Various Muscles

This group saw an increase in parasympathetic activity during trigger point acupuncture.  This is probably a nonspecific effect of needling, but of significance nonetheless!!

Complexity and Aging

As readers know, I’m focused on Heart Rate Variability in the clinic.  It is a perfect example of the complexity this author is talking about.  Within bounds, more variability in heart rate is healthier and and leads to more resilience. I wonder about this quite a bit, whether people’s habits get more routine with age. …

Pulse of Inflammation. HRV and the cholinergic pathway

Pulse of Inflammation. Heart Rate Variability, the cholinergic pathway, and Implications for therapy This paper is not new, but I was unaware of it before.  Tracey outlines some of the correlations between HRV and cytokine levels.  He makes the case that some diseases that are characterized by elevated cytokines, such as rheumatoid arthritis, may have…

Impact of sex and depressed mood on the central regulation of cardiac autonomic function

I think it reads better using “gender” not “sex”. But the conclusion is interesting nonetheless.  I didn’t realize that depression and other mental conditions were more correlated with heart disease in women than men. I’m glad they included HFnorm values, something I can understand.  The full article is behind a paywall, so not available to…

Submission to INS International Neuromodulation Society Conference, Paris

ABstract INS 2020 I will post this here.  With all the uncertainty about Covid 19, the conference may be canceled anyway.  For references, please click on link above ­­Improving autonomic balance by decreasing sympathetic activity and increasing parasympathetic activity is of intense interest in the research community. Improved autonomic balance reduces inflammation implicated in medical…

Use of TAVNS in conjunction with Acupuncture for Anxiety: Ma.Co edition

I’ve been working on trying to get a single HRV measure of efficacy for transcutaneous auricular vagal nerve stimulation.  Readers know that I look at many parameters since the “best use” procedures are far from established.  Some advocate time measures such as RMSSD, others LF/HF a frequency measure that I’ve found to be a great…
