Heart Rate Variability Assessment 

The #1 Risk Factor for Sudden Cardiac Death

Our HRV test can reveal an imbalance between your heart and nervous system in minutes.

HRV training can result in enhanced health and wellness...  

Heart Rate Variability (HRV) evaluates the balancing act between the sympathetic nervous system (fight and flight) and the parasympathetic nervous system (rest and digest). 


An imbalance in HRV is the #1 risk factor for sudden cardiac death. Our simple hand electro-sensor test reveals the balance between your heart and nervous system in minutes. Heart Rate Variability (HRV), as monitored from an individual’s heart rhythm, is the most powerful indicator of both cardiovascular health and general well-being*.


HRV testing is a prognostic (predictive) indicator of cardiac condition, fitness, stress levels, aging, health risk levels, chronic disease condition and more. 


HRV training can result in enhanced health and wellness, as well as an increase in attention, concentration and short term/working memory.

The HRV Process

The Test

The HRV test consists of two main components: a small EKG sensor with a pulse wave sensor and the accompanying analysis software. A five-minute recording of HRV is all that is necessary to quickly create an accurate assessment of the status of the sympathetic and parasympathetic branches of the Autonomic Nervous System.


The Software

The sensor transmits the collected data to the PC for processing. The software uses advanced technology of recording and interpreting HRV signals in order to derive heart rate data. This heart rate data is used to ascertain the current state of inner balance and self-regulatory activity.


The Analysis

The software and analyses are intuitive, easy-to-use and designed for success in the hands of a healthcare practitioner. Simple hardware and standard computer requirements ensure the QHRV test transitions seamlessly into virtually every health practice.

An Effective Predictor

Heart Rate Variability analysis has acquired exceptional popularity over the last few years as one of the most effective predictors of nonspecific health risk. Scientific and clinical studies have established its usefulness in almost all branches of medicine. Level 1 Diagnostics QHRV is a noninvasive, fully automated computer-based system that provides Heart Rate Variability (HRV) and Pulse Wave Velocity (PWV) analysis for a quantitative assessment of the Autonomic Nervous System (ANS) and autonomic balance (sympathetic and parasympathetic).

Heart rate variability (HRV), or the beat-to-beat alterations in heart rate, is an accurate and reliable reflection of the many physiological factors modulating the normal rhythm of the heart. In fact, HRV provides a powerful means of observing the interplay between the sympathetic and parasympathetic Autonomic Nervous Systems (ANS).

The Autonomic Nervous System (ANS) plays an important role, not only in physiological situations, but also in various pathological settings such as diabetic neuropathy, myocardial infarction (MI) and congestive heart failure (CHF). HRV has a high association with the risk for sudden cardiac death, and arrhythmic complications.

Physical and Mental Stress Assessment

The QHRV test also offers the possibility of Accumulative Physical and Mental Stress Assessment. Chronic physical stress and accumulative mental stress are conventional health risk factors, triggering the development of life threatening specific diseases. The Mental Stress Index represents the body’s adaptability to internal and external stressors that are placed on the body every day. Mental Stress Index indicates the function of the ANS. This represents the level of stress the body is experiencing at the present time. If the stress resistance is low it can lead to physical problems and disease. The Physical Stress Index represents the fatigue or activity level of the body from a cellular level.
