According to the principles of relativity, the laws of physics, including biological processes, are the same in all inertial frames of reference. This means that if you are in a spaceship moving at a constant velocity (even if it's 90% the speed of light), your heart rate would appear normal to you, just as it would if you were at rest on Earth. Therefore, from your perspective on the spaceship, your heart rate would still be 60 beats per minute.
