Most muscles in our bodies only act in response to incoming nerve signals, which have to trigger each individual muscle cell to contract or relax. But heart muscle is different. The impulses that ...

This is your heart on an energy drink, and it’s contracting significantly faster than it was before you opened that can full of liquid stimulant. So says a team of cardiac radiologists who were ...

Researchers have identified a previously unrecognized small protein in cells of the human heart that plays a key role in heart muscle contraction. The protein is made from an RNA that was previously ...

In a normal heart rhythm, your heart beats in a steady, even way. The upper part of your heart (atria) squeezes and pushes blood to the lower part (ventricles), pumping blood and oxygen out to the ...
