QHRV is easy to be performed in all medical branches.

QHRV Introduction

Comprehensive Health Assessment

Heart Rate Variability Analysis, has acquired exceptional popularity over the last few years as one of the most effective predictors of non-specific health risk. Scientific and clinical studies have established its usefulness in almost all branches of medicine.
QHRV is a noninvasive, fully automated computer-based system that provides Heart Rate Variability (HRV), blood pressure analysis and Pulse Wave Velocity (PWV) analysis for a quantitative assessment of the Autonomic Nervous System (ANS) and Autonomic Balance (sympathetic and parasympathetic). The innovative technology behind QHRV involves computer analysis of HRV and Autonomic Function Assessment making it useful in most clinical disciplines of medicine.

QHRV is the result of over 30 years of applied scientific research by a team of renowned medical doctors and specialists. At the helm of this research team is Professor Svetoslav Danev, one of the pioneers in HRV analysis theory and clinical verification as well as the first President of the European Society for HRV Analysis.

QHRV offers the possibility of Accumulative Physical and Mental Stress Assessment. Overstress and immobilization are conventional health risk factors, triggering the development of life threatening specific diseases.

QHRV Pulsewave velocity analysis is based on physiological phenomenon, observable and measurable in the arterial elasticity and stiffness during blood circulation.





Designed for Clinicians, by Clinicians

Benefits all Medical Branches Including:

*   Primary Care
*   Cardiology
*   Pulmonology
*   Endocrinology
*   Neurology
*   Pain Management



Heart rate variability (HRV) is an accurate and reliable reflection of the many physiological factors modulating the normal rhythm of the heart. HRV provides a powerful means of observing the interplay between the sympathetic and parasympathetic autonomic nervous systems (ANS). QHRV products encompass the theoretical and clinical applications surrounding HRV analysis with a proven methodology for patient monitoring, tracking and assessment.

QHRV Assessments provide quantitative and qualitative analyses based upon HRV, ANS and Pulsewave analysis. Assessments may include Autonomic Balance analysis, ECG analysis, Cardiovascular Fitness, Pulsewave Velocity and Cumulative Stress analysis. Testing is quick, noninvasive and effective for revealing valuable health conditions, fitness state, response to treatments, stress levels and more.
