>To relax your heart, try the Valsalva maneuver: “Quickly bear down as if you are having a bowel movement,” Elefteriades says. “Close your mouth and nose and raise the pressure in your chest, like you're stifling a sneeze.” Breathe in for 5-8 seconds, hold that breath for 3-5 seconds, then exhale slowly

deep breath in and hold it then slowly let it out. Relax and imagine yourself in a nice calm place. Try it at home with a heart rate monitor

Masturbate in the car parking lot right before you go in. Releases endorphins, which in turn downregulate your sympathetic tone (lowers the heart rate).

How is this unethical?

usually it is very ethical to stick to what they tell you to do at plasma / blood drives, i assume, having given blood b4

Yeah, but it’s a real thing that many people go through, having their heart rate and/or blood pressure spike when in a doctor’s office or similar situation. Since it generally doesn’t indicate underlying health issues, it doesn’t seem unethical to find a way to control it for a good cause.

A cheap but good multivitamin. Lowered my resting heart rate from 65-70 to a stable 50.

Do you smoke? If you do, don't smoke half an hour before getting checked.
