Right side cervical Ultrasound VNS (Instructions on how in VagusSkool.com - go to Classroom Modules) (Or search neck ultrasound) Could very well help keep your heart younger, and healthier. 20hz in this study seemed to be a good pulse frequency - we will work on that for the Ultrasound system. 20hz + 40hz Ultrasound is going to be awesome !
The vagus nerve has emerged as the master regulator of cardiac longevity. A 2026 study reveals that vagal signaling is essential for shielding the heart against the chronic inflammation that defines biological aging.
In aged models, the loss of vagal tone accelerates cardiomyocyte senescence and interstitial fibrosis. This leads to a precipitous drop in ejection fraction, often from a healthy 65% to a compromised 42%.
The mechanism is strictly biochemical: acetylcholine activates α7 nicotinic receptors on cardiac macrophages. This inhibits the NF-κB and NLRP3 inflammasomes, curbing the release of pro-inflammatory cytokines like IL-1β.
Chronic Vagus Nerve Stimulation (VNS) has been shown to extend cardiac functional lifespan by 18%. By preserving mitochondrial ATP and reducing reactive oxygen species, VNS maintains the heart’s structural integrity.
Human longitudinal data supports these findings. High vagal tone—measured by an RMSSD over 30ms—is linked to a 25% lower risk of heart failure and significantly slower ventricular remodeling.
We are moving toward a future where neuromodulation acts as a biological pacemaker to arrest the aging process itself.
