Autonomic control of the heart — measurable.
NESA improves heart-rate variability and vagal tone — objective markers of autonomic control of the cardiovascular system.
Information for healthcare professionals
Do you recognise yourself?
Heart rhythm and autonomic balance
Like a tuner showing — beat by beat — how balanced the nervous system is. Higher variability (HRV) means better balance and more autonomic reserve; interpretation is up to the specialist.
Self-assessment, not self-diagnosis — discuss with a professional.
Precision and trust — through the autonomic balance of the heart.
Variability (HRV)
Increased heart-rate variability — a marker of healthy autonomic control.
Vagal tone
Strengthened parasympathetic (vagal) tone — linked to better cardiovascular health.
Stress & recovery
Reduced sympathetic stress — support for recovery and sleep quality.
Microcurrents that tune the vagus.
NESA applies controlled low-intensity (0.1–1 mA) low-frequency (1–15 Hz) microcurrents through eight electrodes on the four limbs and one guide electrode. The signal reaches the autonomic nervous system and restores the balance between its sympathetic and parasympathetic branches.
In cardiology this balance strengthens vagal (parasympathetic) tone and raises heart-rate variability (HRV) — validated markers of autonomic control and cardiovascular risk.
Where NESA finds application in cardiology.
NESA makes autonomic balance visible: HRV and vagal tone are measured objectively before and after the protocol.
NESA HRV study (Melián-Ortíz, Brain Sci. 2025): a randomised pilot in 16 women with post-COVID dysautonomia — SDNN and pain threshold improved significantly more with NESA; the authors recommend larger trials. An early, supportive signal. For healthcare professionals.
A clear frame for the treatment course.
A typical course in cardiology. Parameters are adapted individually by the treating specialist and combined with ongoing therapy and monitoring.
Built for cardiology practice.
Cardiology clinics & wards
Centres seeking a non-invasive complement with objective autonomic markers.
Cardiac rehabilitation
Recovery after a cardiovascular event with HRV tracking.
Internal medicine & prevention

Indications, protocols, programmes and clinical data for implementing NESA in your practice.
Short answers for professionals.
Is the therapy safe?
Yes. NESA is a non-invasive, low-intensity method with no known systemic side effects. Sessions are conducted by a trained specialist.
Does it replace cardiology treatment?
No. NESA complements pharmacological treatment and rehabilitation by improving autonomic balance — within standard cardiology care.
How is the effect measured?
Objectively — via heart-rate variability (HRV) and vagal tone (RMSSD), tracked before and after the protocol.
Are there contraindications?
Pacemakers and other active electrical implants, pregnancy and epilepsy require prior medical assessment. When in doubt, consult the treating physician.
Microcurrents through the wrists and ankles — the whole autonomic axis at once.

At the core: programmes P1–P9
Every protocol in this field combines the reference programmes P1–P9 — general homeostasis, body levels, ANS/CNS and targeted nerves — according to the clinical goal.
See programmes P1–P9 →Protocols are guidelines.
Parameters are guides; the therapist adapts them to the patient.
NESA is applied after individual assessment — as part of the overall medical plan.
Absolute contraindications (pacemaker, pregnancy, active electrical implants) follow the device IFU.
Before you invest — the independent assessment.
