Heart check before a race: what it is and why it matters
A pre-race heart check is a quick, non-invasive cardiography you do at rest the day before your Spartan or DEKA. You are about to push your body to the limit, so check the engine first: a few minutes, no effort and the result on your phone.

Why check your heart before a race?
A Spartan or a DEKA takes your heart rate to levels you never reach in normal training, sometimes for hours. Almost all of us train our legs, our strength and our obstacle technique; very few of us have ever looked at how our heart is doing.
The check will not tell you whether you are going to win, but it does give you information about the organ that works hardest on race day. Getting to the start line knowing how your heart is doing is part of your preparation, just like your last training session or your dinner the night before.
What is Cardisio?
Cardisio is a cardiography technology that analyses your heart in 3D from measurements taken at rest. It is not a stress test: you sit down, you do not have to run or pedal, and no prior preparation is needed.
That is why it fits the day before a race: it does not tire you, it does not get in the way of your rest, and it gives you information right when you value it most.
What your heart check report looks like
After the test you receive a cardiography report in your Pulse personal area, showing your heart’s activity in the three spatial planes along with its parameters. You can download it as a PDF and take it to your doctor.

Does it replace a medical check-up?
It is a screening test: it gives you information about your heart, but it does not replace your doctor’s assessment or a sports medical examination. If the report shows something worth looking into, the next step is your doctor.

Heart check before a race: FAQ
What does the heart check involve?
It is a non-invasive cardiography using Cardisio technology, which analyses your heart in 3D from measurements taken at rest. It takes a few minutes the day before the race, at a pharmacy, your hotel or the venue, and the report arrives in your Pulse personal area.
Does it hurt, or do I have to exert myself?
No. It is a non-invasive test done at rest: you sit down for a few minutes and you do not have to run, pedal or exert yourself in any way. That is why it fits the day before a race without tiring you or getting in the way of your rest.
Do I need any preparation?
No. There is no fasting and no warm-up: you can do it the day before the race without changing your routine. Just turn up at your appointment at the pharmacy, your hotel or the race venue, and you are done in a few minutes.
Does the heart check replace a medical examination?
No. It is a screening test that gives you information about your heart, but it does not replace your doctor’s assessment or a sports medical examination. If the report shows something worth looking into, the next step is to take it to your doctor.
Where do I get the result?
In your Pulse personal area. The cardiography report shows your heart’s activity in the three spatial planes along with its parameters, and you can download it as a PDF to keep or to show your doctor.
Can I get it if I am not racing?
