Dr. Evan Matthews, associate professor for exercise science and physical education at the Montclair State University, New Jersey shows us this in the following demonstration:
The GE Case System is sold by GE Healthcare Chicago, USA
The following picture shows a GE Case System:
A device which is built from electronic components as for instance a Cyton board:
and a Raspberry Pi:
is much smaller than an GE Case system.
- If we use a 3 lead ECG device which is gold standard for heart rate measurements, we only need to place 5 electrodes and not 12 as shown in the video above.
- We eventually find also other instructions for ECG devices which show ECG electrode placement for those. There is a big diversity of ECG electrodes and cables available on the market, which can make electrode placement easier and faster.
- An ECG device which is built from a Cyton board, a Raspberry Pi and HeartPy is handier and easier to use than the device shown here.
The CE case system is for medical applications. If we want to build a device with the goal to have only a high heart rate accuracy, the device can be much simpler.
- If we build the ECG device we described on the previous pages we have our own gold standard ECG device for our own scientific studies.
- We only have to analyse the ECG signal we recorded with OpenBCI GUI with HeartPy.
- If we are successful, will we ever use our Polar H10 chest strap or our Apple watch again?
- Eventually only, if intense activities with strong body movements are investigated. And this only until someone solves the problem of ECG movement artifacts.
The demonstration in the last video shows how to use a research grade ECG device in combination with a treadmill. We see here a subject running on it. Is it up do 15 km/h as in the paper of the Cleveland Clinic in Ohio? For faster speeds, we need a reserach grade ECG device which can handle with noisy ECG signals. This one seems not be able to do this.
