I visited my doctor these days, and it was time for an update on my heart performance. Also if you feel healthy, sometimes small things can have big effects on your body – and you would not even notice it. I recommend to do medical check ups on a regular basis to keep updated on the details of your body function. This gives you the option to deal with problems early enough, before they get serious!
With this system (“ECG”= Electrocardiography), as seen in the picture below, my blood pressure and heart rate have been checked during a physical performance test. During biking I was wearing electrodes on my chest and back to test the heart activity, and also a band around my left arm to measure blood pressure.
