How do i keep my heart rate down?

Question

Tomorrow i have the most important hour of my life. I have a medical and if i pass i will get the job of my dreams - being a firefighter. Part of the medical is to perform a step test and the nurse measures my heart rate. I can fail this if nerves get the better of me, despite knowing i am fit enough. Does anyone know of any way i can keep my heart rate down? Any help is extremely gratefully received.

Answer 1

make sure you keep breathing. If you provide your heart with enough oxygen it has less of a reason to pick up it's pace. Relax as much as you can. But the most important thing is keep breathing properly.
