Heart Rate Variability (HRV) is the analysis of the beat-to-beat time intervals of the heart rate. Throughout a 24-hour period the heart rate is continuously adjusted by the autonomic nervous system in response to internal and external triggers like physical activation, stress, relaxation, recovery and sleep.
The autonomic nervous system can be split into two parts:
- The sympathetic nervous system which is activated to ‘prepare’ the human body for physical activity.
- The parasympathetic nervous system (the vagus) which is ‘responsible’ for relaxation / recovery periods / processes e.g. during sleep.
Many regulating systems of the human body are influenced by internal and external rhythms. One of the most significant external rhythms is the ‘day/night rhythm’ (circadian) and so it is not surprising that many of the regulating systems in the body show a circadian rhythm e.g. the mean heart rate during the night is lower than during the day.
The heart is a central point of many regulating systems which means that the heart rate is influenced by many body functions. This is because the heart is controlled by the autonomic nervous system which is the controlling network of the human body.
Decreased autonomic regulation is generally a sign of bad health. Using HRV analysis it is also possible to validate the selected therapy. An increasing heart rate variability (increasing autonomic regulation) shows that a therapy is working.
Heart Rate Variability is a very efficient way to take a closer look into many regulating systems by just measuring the heart rate and can be used in a wide range of diagnostic applications including:
- Sleep quality
- Apnea related hypertension
- Sleep/Apnea related cardiac arrhythmias
- Therapy validation (e.g. after MI)
- Diabetic neuropathy
- Health management
- Preventive medicine
- Optimization of physical training
Medilog Darwin HRV uses high speed sampling and displays the result in simple graphics which can be interpreted easily by general practitioners (GPs), nurses and technicians to see if the patient requires further testing and/ or needs treatment for heart related conditions.
Medilog Darwin HRV puts a reliable, affordable and non-invasive screening device and research tool in the hands of people that can make a difference.
The HRV Power Spectogram shows sympathetic and vagal activity and can be used to indicate your patient’s quality of health and quality of sleep.
Heart Rate Variability is a powerful measure of autonomic nervous system function. Low HRV is considered as an independent marker of mortality risk but it is important to ensure that the beat to beat variation is real, and not caused by inaccuracies of the equipment used to carry out the measurement.
Medilog Darwin HRV provides the best beat to beat measurement available non-invasively and is an ideal tool for screening for autonomic failure, syncope, neuropathy and detailed research into HRV and its associated conditions.
If you haven’t got a Medilog… you can’t do accurate advanced HRV analysis.
Medilog Darwin HRV allows you to:
- Ensure HRV is controlled in hypertensive and diabetic patients
- Predict burn out syndrome and diabetic neuropathy
- Judge your patient’s quality of health
