Avacen Cardiovascular Screening and Stress

Better You Health | Dr. Carolyn Johansen, N.D.



Early detection. Personalized prevention. Whole‑body clarity.

At Better You Health, Dr. Carolyn Johansen uses the FDA‑cleared Avacen Cardiovascular & Stress Screening (CSS) System to uncover hidden patterns in cardiovascular and nervous system function—often long before symptoms become serious.

This non‑invasive screening provides deep insight into how your heart, blood vessels, and nervous system respond to stress, adapt to daily life, and support long‑term health.

What Is the Avacen CSS™ System?

The Avacen CSS™ is an advanced diagnostic screening technology that measures Heart Rate Variability (HRV) using Accelerated Plethysmography.

This allows us to assess:

  • Overall cardiovascular performance

  • Autonomic nervous system balance

  • Stress response and recovery capacity

  • Vascular flexibility and circulation efficiency

The Avacen CSS™ is an:

  • FDA‑Cleared Class II Medical Device

  • CE Marked

  • Clinically validated for cardiovascular and autonomic nervous system screening


Why Cardiovascular & Nervous System Health Matters

Your cardiovascular and nervous systems are deeply connected.

The heart, arteries, veins, and nervous system constantly communicate to regulate:

  • Blood pressure

  • Circulation and oxygen delivery

  • Stress response and recovery

  • Energy levels and endurance

  • Long‑term cardiac resilience

When the nervous system is under chronic stress or stuck in “overdrive,” it places added strain on the heart and blood vessels—often silently and long before symptoms appear.

Understanding this relationship gives you a much deeper, more accurate picture of your true cardiac health.


What the CSS Screening Measures

Cardiovascular Function

  • Heart rhythm stability

  • Circulatory efficiency

  • Vascular elasticity and flexibility

  • Early indicators of cardiovascular strain

Nervous System Function

  • Autonomic balance (sympathetic vs. parasympathetic)

  • Stress adaptation patterns

  • Recovery capacity and resilience

A strong nervous system supports a strong heart. When this balance is disrupted, both systems suffer.


How the Test Works

The Avacen CSS™ screening is:

  • Non‑invasive

  • Painless

  • Radiation‑free

  • Quick and comfortable

Using advanced sensors and HRV analysis, the system records detailed data about how your heart and nervous system respond in real time.

With repetitive screenings over time, Dr. Carolyn can:

  • Track cardiovascular improvements

  • Monitor nervous system recovery

  • Measure the impact of lifestyle changes

  • Detect early warning shifts before symptoms worsen


What You Gain From CSS Screening

After your screening and personal review with Dr. Carolyn, you will understand:

  • How strong and efficient your heart is

  • How flexible and healthy your blood vessels are

  • How your nervous system handles stress

  • Whether your system is balanced, strained, or overworked

This allows us to:

  • Identify priority areas for improvement

  • Detect early cardiovascular and stress‑related risks

  • Personalize lifestyle and wellness strategies

  • Monitor long‑term heart and nervous system resilience
