Our added value in healthcare: Real-time electrocardiogram and remote medical monitoring.

The latest e-health study conducted by Bearing Point defines that the IoT market in healthcare is expected to experience one of the strongest annual growth in the coming years, reaching 137 billion euros in 2022. Patients are increasingly aware of and interested in new technologies as part of improving their care.

Our BodyConnect technology will enable athletes to measure their cardio performance but also caregivers to move to a new level in real-time monitoring of the at-risk or ill subject, regardless of location through telemedicine.

The fields of application of remote monitoring in health are vast: sleep apnea, sudden infant death syndrome, but also diabetes, obesity... Other fields are also opening up to remote monitoring: that of exposed people, i.e. working in a risky environment (nuclear, industrial cleaning) or exposing people, i.e. those who have responsibility for third parties (airplane pilots, train drivers, bus drivers...).

Here are the performances of our ECG in real time as well as parameters extracted thanks to the processing algorithms embedded on the Clicshirt.

Signal name Data rate
ECG(1) 250 ech. /sec. 12 bits Bandwidth 0.67Hz - 40 Hz
HR(2) 1 ech./ 5sec. 8 bits Heart rate

      What is VO2 max?

      Maximum oxygen consumption, or VO2 max, indicates the maximum flow of oxygen that the body is able to absorb to sustain itself during physical effort. It is to the athlete what the engine capacity is to the engine. It is an indicator of physical performance and a limiting factor of athletic capacity, and can be improved by specific training. VO2 max can be considered as a criterion for evaluating physical performance. It gives an indication of the level of fitness and endurance of an athlete. The higher its value, the more the athlete is able to maintain an effort of a certain intensity over time. If the athlete increases his VO2 max through training, he will be able to run either faster for the same distance or longer for the same intensity.

      How to calculate his VO2 max?

      There are several methods, some direct and very complex, requiring a laboratory test, on a carpet or ergo cycle with gas exchangers...or very reliable indirect methods thanks to different VMA tests accompanied by your Clicshirt that will guide you to propose the most suitable calculation according to your personal goals.

      What is MVA?

      MVA (Maximal Aerobic Speed) is the speed at which you reach your maximum oxygen consumption (VO2 max). MVA is a pace that you can maintain for a duration of 4 to 6 minutes. Assessing maximum aerobic speed allows the application to adjust the speed of their session for optimized results.
      The higher your VMA, the more you will be able to run at high speeds before reaching your VO2 Max (Maximum Oxygen Consumption during exercise).
      The Clicshirt offers a list of VMA tests that have proven their effectiveness:
      Cooper, ½ Cooper, light luc....
      Our application also goes much further by offering other physical test with very simple implementation: 10km, half marathon, and for the specialists of the trail we even go so far as to offer you a KV test (more quickly make 1000m of D+). We invite you to go to the test part of your application.

      What does the R-R Interval mean?

      This curve is manifested in the ECG insert of your application. It is simply the representation of the electrical activity of your heart (often referred to as the "PQRS complex").
      It is three waves next to each other following the P-wave, and corresponds to the depolarization of the ventricles (A cardiac ventricle is a compartment of the heart that, when it contracts, ejects blood out of the organ). By definition, the Q wave is the first negative wave, the R wave is the first positive wave in the complex, and the S wave is the first negative wave after the R wave (see diagram below).

      As you can see, the "R" wave which is the sharpest on the diagram, will allow us, thanks to the Clicshirt technology to measure not only its appearance but the time and the time variation between each R peak...this is the famous R-R interval which will open up a field of very useful information for your training and your health.

      What does Heart Rate Variability (or heart rate) mean?

      Heart Rate Variability or HRV or HRV (Heart rate Variability) is a major piece of information to take stock of your state of fitness...and the Clicshirt technology offers you to evaluate it in a very simple way.
      Clicshirt measures the CFV by taking the time between 2 points R of the heartbeat (Cf. R-R Interval) . This time is subject to many factors of adaptation of our nervous system (sympathetic system, parasympathetic ...)
      A high variability indicates a good immediate capacity of adaptation of the heart to the solicitations, and is thus both a sign and a factor of health.

      How to test its VFC?

      Clicshirt offers in this version of the application a first test of state of form of 3'. This test should be done in a quiet place, ideally in the morning in a resting position and especially...always in the same way. It's very important to do it the same way to give reliability to your test.

      Your app will then compare the tests over time and thus be able to evaluate if your body is assimilating your training loads correctly or if you need to lower the load. Your VFC will be a good snapshot of your fatigue status. Essential information for an athlete who wants to measure his progress.

      Why do a recovery test?

      You will notice that after each session your app will offer you a one minute test. We encourage you to do this.
      This test should be done quietly and always in the same way. It will allow you to obtain valuable information on the ability of your heart to return to a resting state quickly. Indeed, if your heart rate returns to an initial state in a short time, it is a sign of good recovery and your training is going in the right direction.

      What is BMI?

      The Body Mass Index (BMI) is a measure used to estimate a person's corpulence and nutritional status. Thus, it helps to determine if their weight is in line with their height and to observe if they are overweight or too skinny.
      The body mass index (BMI) is the only index validated by the World Health Organization to assess the corpulence of an individual and therefore the possible health risks.

      To calculate its BMI, simply divide its weight by its height squared.
      Thus, for a person weighing 60 kg and measuring 1.70 m this gives: 60/ (1.7 x 1.7) = 20.76. Results between 18.5 and 25 indicate a BMI in the normal range. In this example, the person therefore has a correct weight for his height.
      BMI < 18.5 kg/m²: underweight
      18.5 < BMI < 24.9: normal weight
      25 < BMI < 29.9: overweight
      BMI > 30: obesity

      Below 18.5 and above 25, it is advisable to make an appointment with your primary care physician or a nutritionist. Both undernutrition and overweight can have notable health consequences.
