The meaning of HeartRateVariability

The meaning of heart rate variability

Health in images and figures

HeartRateVariability (HRV) is a measure for the complete adaptability of an organism and therefore a measure for health. HRV consists of the millisecond-exact distances between the heart beats of a human being. The change of these intervals is a measure of the ability to regulate the Autonomic Nervous System.

The Autonomic Nervous System manages all essential functional processes in the human organism. The interaction between its two branches – Sympathetic Nervous System for performance and Parasympathetic Nervous System or Vagus for regeneration – can be captured and visualised by measuring the HeartRateVariability.

How does a HRV measurement work?

We measure HRV with the help of a little HRV recorder which is attached to your chest by two adhesive electrodes. Even with the recorder, you can still follow your daily routine – free time, sports, work, sleep – without interruption.

Immediately after the application, the measurement starts automatically. After the end of the recording, the data is transferred to the computer via the integrated USB port.

Why should I measure for 24 hours?

HeartRateVariability offers essential information even during a short-term measurement of five minutes. Measurements of 24 hours allow for a dynamic view of the functional daily physiology of a human being and their adaptive-anticipative reaction pattern. The extent of the adaptability to stress can be deduced from regular, interdependent biological patterns.

What kind of results do I get?

Using a mathematical method, our software will transform the approx. 100,000 heart beat data of a 24h measurement into a diagram. The colour display of the diagram is similar to a fire. The more intense and dense the colours (blue, red, yellow etc.) and the higher the “flames” in the “LifeFire” (Lebensfeuer) blaze, the higher the HRV and therefore fitter and more vital the person is currently.

Short- and long-term measurements 95%
Time- and frequency-ranges 92%
Medical background knowledge 85%
Longstanding expertise in HRV 90%

Our Software

With every mouse click, our software provides detailed, statistically edited gender- and age-correlated results on all time- and frequency-ranges of HRV (min/max HR, avg. HR, Total Power, VLF, ULF, LF, HF,…) and all important graphics (HRV-spectrogram, “Lebensfeuer”, pulse curve, respiration, pulse-respiratory quotient, scatter plot, histogram, tachogram) including zoom functionality.
Using Click&See, activities can be analysed comprehensively and HRV data looked at any period of the measurement. Based on physiological regularities, the referenced algorithms of the software calculate over 100 results in the form of (traffic light) graphics and numeric figures and, if requested, an up to 50-paged PDF report per measurement. Our HRV analysis is constantly being re-developed, has a 6-way filter system and utilises a databank of more than 24,000 measurements.
