Our heart beat increases in space because of a decrease in fluid volume and changes in myocardial Mass. Blood pressure is also lower in space than on earth. The cardiac output of the heart - the amount of blood pumped out of the heart each minute - decreases in space, too.

⚡ When astronauts spend long periods of time at zero gravity in space, their hearts become more spherical and lose muscle mass, a new study finds, which could lead to cardiac problems.
✨ The heart doesn't work as hard in space, which can cause a loss of muscle mass," study leader Dr. James Thomas, Moore Chair of Cardiovascular Imaging and Lead Scientist for Ultrasound at NASA, said in a statement. "That can have serious consequences after the return to Earth, so we're looking into whether there are measures that can be taken to prevent or counteract that loss.
